Bathroom Remodel Costs in Johnston, Iowa (2026 Guide)
Thinking about a bathroom remodel in Johnston this year? With local home values strong and the Polk County market competitive, an updated bathroom can pay off. This guide covers...
Ames homeowners expect things done right. Iowa State University brings an educated, detail-oriented community to Story County , and that same standard carries over into home improvement decisions. If your tile grout is cracking, your exhaust fan is cycling moisture into the ceiling, or your bathroom has looked the same since the mid-1990s, that is a daily quality-of-life problem that compounds every morning.
Ames has a mix of older campus-area homes, mid-century ranches, and newer residential growth on the city’s west and south sides. Each era brings its own bathroom challenges , galvanized supply lines, fiberglass surrounds at end-of-life, and exhaust fans that never made it to the exterior.
Busy Builders fixes Ames bathrooms the right way: waterproofing first, tile second, no shortcuts, and a written estimate before any demo begins.
Since 2020, Busy Builders has completed 1,285+ remodeling and construction projects across Central Iowa, including bathroom remodels throughout Story County and the greater Ames community.
Ames has one of the most engaged homeowner bases in Central Iowa. The ISU community values durable, low-maintenance materials , water-resistant tile, LVP flooring, and properly waterproofed wet zones over soft goods that wear quickly. Older campus-adjacent homes often have cast iron drain lines, galvanized supply pipes, and exhaust fans routed to the attic instead of the exterior. These are not cosmetic problems. They are structural ones that have to be resolved before any new tile goes in.
We assess each Ames bathroom as its own project. We tell you what has to go, what can stay, and what it will cost before a single tile comes off the wall.
Honest pricing, a clear written scope, and no surprise charges on every bathroom remodeling project in Ames and across Central Iowa.
We walk through your bathroom before any estimate is produced. We check where the plumbing runs, whether the exhaust fan vents to the exterior, and what the tile is covering underneath. Older Ames homes frequently have moisture damage inside the walls that is invisible until demo begins.
We will not sell you a scope your bathroom does not need.
We want to be the registered contractor that Ames homeowners call first for bathroom remodeling in Central Iowa and recommend to their neighbors without hesitation.
Ames is a community that values transparency and does its homework before hiring anyone. We match that standard. Every project starts with a full walkthrough, a written scope, and a fixed estimate. ISU Extension is a trusted local resource for Iowa housing guidance, and we build every bathroom to hold up in Story County’s climate , hot humid summers, cold dry winters, and everything in between. We build each one to last.
Before any demo begins, we walk through your bathroom from floor to ceiling. We check tile condition, subfloor integrity, moisture history, exhaust fan routing, plumbing locations, and existing electrical circuits.
Ames homes built before 1990 , and there are many, particularly near campus and in the older neighborhoods on the north and east sides , frequently have exhaust fans routed into the attic rather than to the exterior. That single detail causes more mold problems, recurring grout failures, and ceiling stains than almost any other bathroom issue we find in Story County homes. We catch it here, before a single wall opens.
Permit requirements through the City of Ames are confirmed for your specific scope before anything is quoted. You receive a written scope of work and a written timeline before we touch a single tile. For a full picture of what to expect, review our guide on bathroom remodeling in Ames in 2026.
Demo is where the real condition of an Ames bathroom becomes visible. Water damage behind shower surrounds, rotted subfloor beneath leaking tub drains, corroded supply lines inside walls, and mold colonies seeded by years of attic-venting exhaust fans all surface here.
Iowa’s humidity swings accelerate damage behind improperly waterproofed tile. What looks like a grout problem on the surface is often a substrate problem underneath. We do not cover up what we find. Every moisture problem, subfloor failure, or corroded line is addressed before rebuilding begins.
This is also the stage where hidden conditions get confirmed. Budgeting a 15-20% contingency for any Ames home built before 1990 is not overcautious , it is accurate. See our full breakdown on evaluating bathroom remodeling costs and benefits before your project begins.
Moving a toilet, adding a second sink, or relocating a shower drain all happen while the walls and floor are open. This is the lowest-cost window for layout changes. Waiting until after walls close adds $3,000-$10,000 and weeks to the timeline.
All plumbing rough-in work is performed by state-licensed plumbers and inspected before walls close. We also replace corroded galvanized supply lines and upgrade shutoff valves at this stage. Older Ames homes , particularly those built in the 1950s through 1970s near campus , frequently have galvanized supply lines still in service. These are found at demo and replaced before new plumbing is roughed in.
Plumbing relocation is the single biggest cost driver in any bathroom remodel. Keeping the existing plumbing layout saves $3,000-$10,000 on most projects. Busy Builders walks through that decision at every consultation. You can also review our guide to bathroom remodeling costs in Central Iowa for a full cost breakdown by scope.
Electrical rough-in covers new circuits, outlet placement, lighting wiring, exhaust fan wiring to the exterior, and heated floor connections where scoped.
Iowa NEC 2023 requires GFCI protection on every bathroom outlet , not just those near the sink. In Ames homes built before 1980, this step often uncovers aluminum wiring, undersized panels, or missing GFCI protection throughout the bathroom. All of it is brought up to current code before drywall goes up.
All electrical work is performed by state-licensed electricians, pulled with permits, and inspected before any wall surfaces close. The exhaust fan is wired to exterior venting at this stage , never into the attic, where moisture accumulates and feeds mold inside the ceiling cavity over time.
Waterproofing is the step that determines whether a bathroom lasts five years or twenty-five. It is also the step most homeowners never see after the project is complete , which is exactly the point.
Busy Builders applies a waterproofing membrane behind all tile in showers, tub surrounds, and wet walls. Cement backer board is installed and seams are properly lapped before any tile begins. Tile and grout are not waterproof. The membrane is. Iowa’s seasonal humidity swings create constant pressure on grout lines, and contractors who skip membrane installation produce showers that fail within three to seven years.
Subfloor is leveled, repaired, and fully prepped before any tile or flooring is installed. Skipping subfloor prep is a leading cause of tile failures in Story County bathrooms. For more on choosing the right flooring materials for Iowa homes, see our guide to Iowa flooring options including LVP, hardwood, and tile. We do not skip the prep.
Tile selection matters in Ames, where Iowa’s thermal range runs from subzero winter lows to humid summer highs. We set floor tile, shower tile, and accent tile with proper layout, spacing, and grout selection built to handle Story County’s hard water and seasonal humidity swings.
Floors over unheated spaces and tile near exterior walls face the most stress from Iowa’s freeze-thaw cycles. We use thinset and sealers rated for Climate Zone 5A conditions on every Ames project. For non-tile areas, luxury vinyl plank and heated floor systems are installed during this step.
Read our guide on Iowa flooring options: LVP, hardwood, or tile to understand which materials hold up best in Central Iowa bathrooms.
Moisture-resistant drywall goes on all bathroom walls in every Ames project we complete. Standard drywall fails quickly in high-humidity spaces, so we use cement board in wet zones and moisture-resistant drywall throughout dry areas.
Ceilings are finished smooth and primed for paint. Iowa code requires a minimum ceiling height of 7 feet for habitable bathroom space. We plan every Ames bathroom around existing structural constraints to maximize usable height without costly framing changes.
Proper drywall and backer board selection is one of the details that separates a bathroom that holds up for 20 years from one that shows problems in three.
Vanity, toilet, mirrors, and cabinetry go in once tile and drywall are complete. We set countertops, mount sinks, connect plumbing, and install all cabinetry level and secure.
Fixture selection happens during the planning stage so lead times do not delay the project. Tile is the most common schedule variable in Ames bathroom remodels , ordering early prevents hold-ups.
This is the step where an Ames bathroom stops looking like a construction zone and starts looking like the finished room you planned from day one.
Painting happens after tile and cabinetry are complete, so walls can be cut in cleanly around everything already in place. We use moisture-resistant bathroom paint on every Ames project. Standard interior paint peels and stains within a year in a humid Iowa bathroom.
Exhaust fan installation and final ductwork connection to the exterior also happen at this step. Many Ames homes built before 1990 have exhaust fans venting into the attic rather than outdoors. That mistake saturates insulation, feeds mold inside ceiling cavities, and causes grout failures that look like tile problems but are actually ventilation problems. We never route exhaust into the attic, regardless of how the original setup was configured.
For more on why proper exhaust venting matters in Iowa homes, Energy.gov’s bathroom ventilation guidance explains the long-term impact of correct exterior venting.
Final finishes are the details that make everything feel intentional and complete. Towel bars, toilet paper holders, robe hooks, outlet covers, light switch plates, mirror mounting, and door hardware all go in at this stage.
We do a detailed walkthrough with the homeowner to check every surface, every connection, and every finish before we call the project done. Permits are closed out where required, and final inspections are coordinated with the City of Ames Building Department.
Most Ames bathroom remodels run 3 to 8 weeks from start to finish. Read our guide on how to prepare your Iowa home for a remodel so you know exactly what to expect before demo begins.
Since 2020, Busy Builders has completed 1,285+ projects across Central Iowa with a 99% satisfaction rate. Every bathroom remodel in Ames starts with a full walkthrough, a written scope, and a fixed estimate, so homeowners know exactly what they are getting before demo begins.
Costs depend on room size and scope. A half bath cosmetic refresh in Ames runs $6,500-$16,000. A full bathroom mid-range remodel, the most common scope in Central Iowa, runs $12,700-$30,000. A primary suite overhaul runs $22,500-$35,000+, with luxury projects reaching $70,000-$100,000.
Labor is 40-65% of total cost. The biggest single cost driver is plumbing relocation. Keeping existing plumbing in place saves $3,000-$10,000 on most projects. Always budget 15-20% contingency for Ames homes built before 1990. Demo surfaces problems that were not visible at the walkthrough.
See our complete breakdown of bathroom remodeling costs in Central Iowa for a full scope-by-scope guide.
Timeline depends on scope. A cosmetic refresh, new fixtures, vanity swap, and paint, runs 1 to 3 weeks. A mid-range remodel with tile replacement and plumbing updates typically takes 3 to 6 weeks. A major overhaul with layout changes or structural work runs 5 to 8 weeks.
Add 1 to 3 weeks for permit processing in Ames. The City of Ames Building Services Department handles permits for work within city limits, and processing times vary by project scope. Tile lead times are the most common schedule variable. We order materials early to keep the schedule on track.
Busy Builders builds a written timeline for every project and updates Ames homeowners at every phase transition. No surprises on schedule, just like no surprises on price.
Yes, for any scope that moves or adds plumbing, relocates electrical circuits, adds an exhaust fan on a new circuit, or touches structural walls.
Cosmetic updates, new fixtures, paint, mirror swaps, and flooring over existing substrate, typically do not require a permit. Any work beyond cosmetic scope does. Skipping required permits creates problems at resale, with insurance, and with lenders that cost far more than the permit itself.
Iowa requires any contractor earning $2,000 or more annually to hold active registration with Iowa DIAL under Iowa Code Chapter 91C. Busy Builders is fully registered. You can verify our registration at Iowa DIAL before signing any contract. We pull all permits and schedule all inspections as part of every project scope.
The right answer depends on your household and how many tubs are in the home. If the bathroom being remodeled has the only tub in the house, keep it. A significant share of buyers with young children require at least one tub, and removing the only tub can hurt resale in the Ames market.
If a second tub exists elsewhere in the home, converting the primary bath to a walk-in shower is almost always the better call. Curbless designs, frameless glass, and a built-in niche are the current standard in Ames bathroom remodels. They maximize perceived space and are the most requested upgrade we see from Story County homeowners.
Read our full breakdown in the shower or tub value guide for Iowa homeowners to see how the decision plays out by home type.
Mid-range bathroom remodels currently deliver approximately 80% ROI at resale, the highest figure since 2007, according to the Zonda 2025 Cost vs. Value Report. Upscale remodels return closer to 37%. High-end finishes serve the homeowner’s enjoyment, not the appraiser.
In Ames, the upgrades that return the most at resale are walk-in showers with proper waterproofing and tile, double vanities, and updated lighting. Keep total bathroom spending under 10-15% of home value to avoid over-improving for the neighborhood.
Quality waterproofing behind tile is the most important upgrade buyers will never see, but it protects the value of everything visible above it. Read more about evaluating bathroom remodeling costs and benefits before committing to a scope level.
We seal off the work area with plastic barriers to contain dust and debris from the rest of your home. Floors and hallways leading to the bathroom are protected from traffic and tool movement throughout the project. Crews clean up at the end of every workday.
A bathroom remodel happens inside your home, and we treat it that way. Ames homes with older housing stock, particularly those built before 1990, may have lead paint or asbestos in existing tile, drywall compound, or flooring adhesive. Busy Builders identifies these conditions during the walkthrough and handles them properly before demo begins.
