A bathroom is the smallest room that touches every trade in the house, which is why the quotes for the same room can land $40,000 apart. This 2026 guide uses the ranges Busy Builders has actually quoted in Central Iowa, the code items that fail inspection most, and the one line item (scope added after the first estimate) that turns a $15,000 bath into a $25,000 one.
TLDR: Busy Builders has quoted Central Iowa bathrooms from about $3,000 to $5,000 for a light hall-bath facelift up to about $60,000 for a large primary bath; a typical three-quarter to full remodel without moving fixtures lands around $15,000 to $20,000. Labor runs 40 to 65 percent of the total. Estimates are set up front; the most common reason a bathroom grows is scope added after the first number. Walk-in showers dominate, waterproofing behind tile is mandatory, and every outlet needs GFCI protection. Final costs vary by scope, materials, complexity and location within our service area.
You step into your bathroom every morning and notice the same things: dated tile, inefficient layout, fixtures that have seen better days. A bathroom remodel has been on your list for years, but you need to know what it actually costs and whether the investment makes sense.
The good news? Bathroom remodels are delivering their best returns in 18 years. The key is spending wisely on updates that matter while avoiding costly mistakes that eat into your budget.
What Does a Bathroom Remodel Cost in Des Moines?
Short answer: about $15,000 to $20,000 for a typical full remodel that keeps the fixtures where they are, based on what Busy Builders has quoted across the metro. The band runs from about $3,000 to $5,000 for a facelift (vanity, faucet, toilet, lighting, paint) to about $60,000 for a large primary bath with a tiled walk-in shower, frameless glass, custom double vanity and moved plumbing. The size and scope tables below show where the money goes inside that band.
Bathroom remodeling costs depend on room size, scope of work, and finish quality. Here’s what Central Iowa homeowners typically spend:
| Bathroom Type | Size | Cost Range |
|---|---|---|
| Half Bath | 20-30 sq ft | $6,500 to $16,000 |
| Full Bath | 40-60 sq ft | $12,700 to $18,000 |
| Large Bath | 100-120 sq ft | $19,000 to $21,500 |
| Primary Suite | 130+ sq ft | $22,500 to $35,000+ |
Project scope matters as much as size:
| Project Type | Cost Range | What’s Included |
|---|---|---|
| Basic/Cosmetic | $6,000 to $15,000 | New fixtures, paint, existing layout |
| Mid-Range | $15,000 to $30,000 | Tile shower, semi-custom vanity, new lighting |
| High-End | $30,000 to $80,000+ | Custom cabinetry, layout changes, luxury finishes |
Labor accounts for 40-65% of total project costs. Plumbing work alone runs $800-$5,500 depending on complexity.
Illustrative scenario: An Ankeny homeowner updated a small hall bath for $11,500, new vanity, LVP flooring, and a prefabricated shower unit. By keeping the layout and plumbing in place, they avoided $3,000-$4,000 in extra costs.
Tip: Get detailed quotes that break out labor versus materials. This helps you compare contractors accurately and identify where costs can be adjusted.
Bathroom Remodel ROI: What the Data Says
The national Cost vs. Value report has ranked a mid-range bathroom remodel among the stronger-returning interior projects for several years running, and consistently ahead of upscale bathroom projects. The exact percentage moves every year and by region, so treat any single number as a snapshot. The pattern that holds: a well-chosen mid-range remodel keeps most of its value at resale, and luxury finishes keep less of theirs.
| Project type | How it tends to hold value | Why |
|---|---|---|
| Minor updates | Best percentage return | Low cost, visible change |
| Mid-range remodel | Strong, consistently above upscale | Buyers pay for clean and current, not exotic |
| Upscale or luxury | Lowest percentage return | Personal taste, high cost, narrow buyer pool |
Illustrative scenario: A Waukee family invests $25,000 in a mid-range primary bathroom remodel, new tile shower, double vanity, updated lighting, and fresh flooring. When they list 18 months later, the updated bath is the room buyers photograph, and the home shows better than comparable listings.
Tip: Mid-range improvements outperform luxury upgrades on a percentage basis. A $25,000 remodel that keeps most of its value beats a $75,000 luxury project that keeps well under half.
Why a $15,000 Bathroom Becomes $25,000
Short answer: scope added after the first estimate. On Busy Builders bathroom jobs the estimate is set up front, and the most common reason a project grows is the homeowner expanding the plan once the first number makes it real: a heated floor, a second vanity light circuit, a frameless door instead of semi-frameless, a niche and a bench, a fixture that moves. Each is small. Together they are a week and $8,000 to $10,000.
| Added after the estimate | Typical added cost | What else it moves |
|---|---|---|
| Heated floor | $1,500 to $3,000 | Electrical circuit, tile schedule |
| Second vanity light or sconces | $400 to $900 | Rough electrical, drywall patch |
| Frameless glass instead of semi-frameless | $1,500 to $3,000 | Measured after tile; adds a week |
| Moving the toilet or vanity plumbing | $1,500 to $4,000 | Floor opens, rough plumbing inspection |
| Niche, bench, custom trim | $600 to $2,000 | Framing before backer board |
Two full bathroom remodels we completed in 2026 were reviewed by the homeowners, one a repeat customer, and both ran on the scope they signed. The difference was a fixture list with model numbers before the estimate, not after. Our guide to bathroom remodel timelines shows the same effect on the calendar.
Code Requirements You Need to Know
Bathroom remodels must meet International Residential Code requirements. Failing inspections delays projects and adds costs.
Electrical Requirements (2023 NEC)
All bathroom outlets require GFCI protection, no exceptions. Additional requirements include:
- Dedicated 20-amp circuit for bathroom receptacles
- Outlets within 3 feet of each sink basin
- Tamper-resistant receptacles required
- Ceiling-mounted light fixture controlled by wall switch
Ventilation Requirements
Bathrooms need either mechanical ventilation or an operable window:
- Minimum 50 CFM intermittent fan OR 20 CFM continuous
- Must vent directly outdoors (not into attic)
- Bathrooms over 100 sq ft need higher CFM ratings
Illustrative scenario: An Urbandale homeowner’s bathroom remodel failed inspection because the exhaust fan vented into the attic instead of outdoors. Correcting the ductwork added $800 and a week to the project timeline.
Clearance Minimums
| Fixture | Minimum Clearance | Recommended |
|---|---|---|
| Toilet (side) | 15″ from center to wall | 17-18″ |
| Toilet (front) | 21″ to any obstruction | 30-36″ |
| Shower interior | 30″ x 30″ | 36″ x 48″ |
| Between double sinks | 30″ center-to-center | 36″+ |
Why Waterproofing Is Non-Negotiable
Here’s what most homeowners don’t realize: tile and grout are NOT waterproof. Grout is porous, and water penetrates through capillary action. Without proper waterproofing behind tile, water reaches the substrate and causes mold, mildew, and structural damage.
Waterproofing methods include:
- Liquid membranes: Roll-on application, easiest and most affordable
- Sheet membranes: Plastic or elastomeric sheets bonded with thinset
- Foam backer panels: Waterproof surface that doesn’t absorb moisture
Tip: Never skip waterproofing to save money. Fixing water damage behind tile costs $8,000-$15,000 or more. Proper waterproofing adds $500-$1,500 upfront.
Illustrative scenario: A Grimes homeowner installed a beautiful marble tile shower without waterproofing the substrate. Within two years, black mold grew behind the walls. Complete tear-out and remediation cost $12,000, four times what waterproofing would have cost.
2026 Bathroom Design Trends
Walk-in showers and wet rooms dominate bathroom design this year. Wet rooms now represent a growing share of bathroom projects.
What’s trending:
- Frameless glass shower enclosures
- Curbless/barrier-free shower entries
- Large-format tile (fewer grout lines)
- Linear drains for clean aesthetics
- Built-in niches and seating
- Matte black and champagne bronze fixtures
What’s fading:
- Standard tub/shower combos
- Small mosaic tiles (too many grout lines)
- High-polish stone in showers (slippery)
- Ceramic tile (porcelain more durable)
Tip: Choose porcelain over ceramic tile for wet areas. Porcelain is denser, more water-resistant, and less prone to chipping.
Permits and Iowa Contractor Requirements
Most bathroom remodels require permits for electrical, plumbing, or structural work. Cosmetic updates like paint and hardware typically don’t need permits.
Iowa requires contractors earning $2,000+ annually to register with DIAL (Department of Inspections, Appeals, and Licensing). Verify registration at dial.iowa.gov before hiring. Plumbers and electricians need separate state licenses.
Illustrative scenario: A West Des Moines family hired an unregistered contractor who refused to pull permits for a bathroom remodel. Halfway through, the city flagged the project, work stopped for two weeks, and they paid an additional $1,200 in permit, re-inspection, and correction costs.
Tip: Ask your contractor who is pulling permits and scheduling inspections. If they dodge the question, that’s a red flag.
Critical: Ask for proof of workers’ compensation insurance. If a contractor doesn’t carry it and a worker gets injured on your property, you could be liable.
Frequently Asked Questions
Q: How much does a bathroom remodel cost in Des Moines? A: Busy Builders has quoted from about $3,000 to $5,000 for a hall-bath facelift up to about $60,000 for a large primary bath. A typical full remodel without moving fixtures lands around $15,000 to $20,000. These are quoted ranges and planning estimates; actual costs vary.
Q: What ROI can I expect from a bathroom remodel? A: The national Cost vs. Value data ranks mid-range bathroom remodels among the stronger-returning interior projects and well ahead of upscale ones, but the percentage changes yearly and by market. No return is guaranteed; a clean, current bathroom sells the house faster more reliably than it raises the price.
Q: Do I need permits for a bathroom remodel? A: Yes, for plumbing, electrical, or structural changes. Cosmetic updates like paint, mirrors, and hardware typically don’t require permits.
Q: How long does a bathroom remodel take? A: Two to three weeks of on-site work for a full remodel on a locked scope, inside a five to eight week window from estimate to done. Shower glass is measured after tile and lands last. Layout changes or scope added mid-job stretch it to four weeks on site or more.
Q: Is waterproofing really necessary for showers? A: Absolutely. Tile and grout are not waterproof. Without proper membrane waterproofing behind tile, water causes mold and structural damage that costs $8,000-$15,000+ to fix.
