## What Is a Walk-In Shower Conversion?

A walk-in shower conversion removes an existing tub and puts a shower in its place. Some conversions drop in a prefab pan and surround. Others build a full custom tile shower with a bench, niche, and glass panel. Both use the same footprint, so plumbing usually stays put and cost stays down.

It fits homeowners who step over a tub wall they never fill, and anyone planning to stay in the home as they age. One honest caution first: if this is the only tub in the house, removing it can narrow your future buyer pool. We will tell you when that matters. See [our full bathroom remodeling service](https://busybuildersiowa.com/bathroom-remodeling/), or read our comparison of [walk-in showers versus bathtubs for Iowa homes](https://busybuildersiowa.com/walk-in-shower-or-bathtub-need-to-know-2026/).

- Frequently Asked Questions

## Why Convert to a Walk-In Shower?

### No More Stepping Over a Wall

A low or curbless entry is easier every single day, and it is the change people wish they had made years earlier.

### Uses the Space You Already Have

Same footprint, same plumbing wall. That is why a conversion costs a fraction of moving the bathroom around.

### A Bathroom That Ages With You

Curbless entry, a bench, and blocking for grab bars now means no second remodel in fifteen years.

### Easier to Clean

No tub ledge collecting grime. Glass and tile with proper waterproofing wipe down in minutes.

### Honest Advice on Resale

If it is your only tub, we say so. Bathroom projects recoup about 50 percent at resale on average per NAR 2025, and buyer pool matters.

### Built Waterproof, Not Just Pretty

Membrane behind the tile, correct slope, licensed plumbing. The parts you cannot see are the parts that fail.

- Home Additions Step By Step

## How We Convert Your Tub to a Walk-In Shower

Step #1

### ASSESSMENT & LAYOUT

We look at the existing tub, the plumbing behind it, and the framing under it. Most conversions keep the same footprint, which keeps cost down. If the drain has to move or the subfloor is soft, you hear about it before you get a number, not after demo.

- Existing plumbing and drain checked
- Subfloor and framing evaluated
- Written scope and budget

Step #2

### DESIGN & SELECTIONS

Prefab or custom tile is the fork in the road, and it drives most of your budget. We walk you through pan options, tile, glass, niches, and whether a bench or a curbless entry makes sense for how you will use it in ten years.

- Prefab vs custom tile compared
- Tile, glass, and niche selections
- Curbless option discussed early

Step #3

### DEMO & SUBFLOOR REPAIR

The tub comes out and we find what has been hiding behind it. Old tubs leak quietly for years, so soft subfloor and rot are common. We repair what we find and document it, rather than tiling over a problem.

- Tub and surround removed
- Rot and soft subfloor repaired
- Findings documented for you

Step #4

### PLUMBING & ELECTRICAL ROUGH-IN

A licensed Iowa plumber sets the drain and valve for shower use. Electrical work brings outlets to GFCI protection and confirms the exhaust fan vents outdoors, both Iowa code requirements. Inspections pass before anything gets covered.

- Licensed plumber sets drain and valve
- GFCI protection confirmed
- Fan vented outdoors, not the attic

Step #5

### WATERPROOFING & PAN

This is the step that decides whether the shower lasts. A full waterproofing membrane goes on behind the tile, because tile and grout are not waterproof by themselves. The pan is sloped correctly to the drain so water never sits.

- Waterproof membrane installed
- Pan sloped correctly to drain
- Code compliant assembly

Step #6

### TILE, GLASS & WALKTHROUGH

Tile goes up, glass goes in, and fixtures get set and tested. We clean the space and walk it with you, water running, before we call it done. Written warranty on workmanship (details provided in your contract).

- Tile and glass installed
- Fixtures set and water tested
- Final walkthrough together

## Permits, Code, and Waterproofing in Iowa

Iowa code sets a minimum shower compartment of 1,024 square inches that can hold a 30 inch circle, which works out to about 32 by 32 inches of floor area. Waterproofing behind the tile is a code requirement, because tile and grout are not waterproof on their own. Every bathroom outlet needs GFCI protection under the 2023 NEC with Iowa amendments, and exhaust fans must vent outdoors, never into the attic. Plumbing work is performed by a licensed Iowa plumber. We are registered with [Iowa DIAL](https://dial.iowa.gov/) and pull permits through your city building department, including [bathroom remodeling in Johnston](https://busybuildersiowa.com/locations/bathroom-remodeling-johnston-ia/) and across the metro.

- Frequently Asked Questions

## FAQs About Walk-In Shower Conversions in Central Iowa

How much does a tub to shower conversion cost in Central Iowa?

A prefab or kit conversion runs $1,500 to $5,000. Custom tile runs $3,500 to $15,000 depending on tile, glass, and plumbing moves. Add a 10 to 15 percent contingency. Your written estimate sets the real number.

Should I remove my only bathtub?

Be careful here. Removing the only tub in a one-bath home narrows your buyer pool, regardless of neighborhood. If you have another tub elsewhere, converting this one is usually an easy call. We give you the honest read for your house.

How long does a walk-in shower conversion take?

Most conversions run inside the normal bathroom window of 3 to 8 weeks, and simple prefab swaps land at the short end. Custom tile with plumbing moves takes longer. Waiting on tile or glass can add time.

Do I need a permit for a shower conversion in Iowa?

Usually yes, especially when plumbing or electrical work is involved, and plumbing must be done by a licensed Iowa plumber. We handle the permit through your city building department so nothing gets flagged later.

How small can a walk-in shower be?

Iowa code requires at least 1,024 square inches of interior area that can accommodate a 30 inch circle, roughly 32 by 32 inches. We can work at that minimum, but we will show you what a few more inches buys in comfort.

Will a walk-in shower leak over time?

Not if it is built right. Tile and grout are not waterproof, so a proper membrane behind the tile plus correct pan slope is what keeps water where it belongs. That assembly is code, and it is where cheap installs cut corners.
