Upgrade Your Bathroom: Tub-to-Shower Conversion Guide

Thinking of swapping out that outdated bathtub for a sleek, walk-in shower? Whether you're upgrading for style, space, or accessibility, this transformation can give your bathroom a whole new feel.

Before you start tearing things out, here’s a complete DIY guide to replacing your tub with a walk-in shower — no plumbing degree required (but you might want a plumber’s number just in case).

Is a Walk-In Shower Right for You?

While a walk-in shower offers convenience and a contemporary vibe, it's not ideal for every household. Here are some things to keep in mind:

👨‍👩‍👧‍👦 Your Family

Have small kids or planning for some in the future? A tub might be a must-have for bath time. Pet parents also benefit from tubs for quick cleanups.

🛁 Your Bathroom Layout

If this is your only bathtub, removing it could affect resale value. Most buyers still prefer at least one tub in the house, especially for families.

💸 Your Budget

Tub-to-shower conversions range widely in cost. Kits, tools, possible plumbing updates, and waste disposal add up. Plan carefully, and don’t forget to factor in cleanup costs like a rented dumpster.

Tub-to-Shower Conversion Costs

Expect to spend anywhere from $800 to $15,000, depending on the shower size and materials. Here’s a quick breakdown:

• Shower Kit: $1,000–$8,000

• Tiled Shower: $3,500–$15,000

• DIY Savings: Approx. $1,000 in labor costs

Step-by-Step: How to Convert a Tub Into a Walk-In Shower

1. Gather Your Tools

Be ready with all materials before you begin. You’ll need:

• Plywood (to protect flooring)

• Tape measure

• Flathead & Phillips screwdrivers

• Wrench & Allen wrench

• Utility knife & putty knife

• Drywall saw & reciprocating saw

• Jigsaw

• Pry bar

• Level

• Caulk & caulking gun

• Safety gear (gloves, goggles, mask)

• 10-yard dumpster

2. Measure and Plan Your Space

Installing your shower where the tub was will save time and money. Use existing plumbing lines whenever possible.

Minimum Space Requirements:

• Shower footprint: 30” x 30”

• Ceiling height: At least 80”

• Toilet clearance: 15” from the side, 21” from the front

• Door swing clearance: Leave room if using a swinging door

3. Choose Your Shower Design

Walk-in showers come in a variety of styles. You can go for a DIY shower kit or build a custom tiled look.

Shower Kit Comparison:

Type Description Pros Cons Avg. Cost

Curbed Low edge to step over into the shower Easy to install, affordable May not be ideal for mobility issues $600–$1,000

Curbless Seamless, flush with floor Great accessibility & design More expensive, complex install $1,800–$4,000

4. Remove Wall Sections and Tile

Prepping the area is key. Remove enough wall space around the tub to free it from its position.

Prep Checklist:

• Cover floors with plywood

• Shut off water supply

• Remove drain cover, knobs, faucet

• Disconnect main & overflow drains

• Score grout, then pry tiles off

• Cut drywall or plaster 8” above tub with care

5. Remove the Bathtub

Once the walls are prepped, it’s time to say goodbye to the tub.

Steps to Remove the Tub:

• Remove any fasteners attaching the tub to wall studs

• Cut caulk at base

• Pry the tub away from the wall

• Carefully stand and carry it out (get help!)

• Toss it in the dumpster

• Inspect & repair any subfloor damage

6. Install Your New Walk-In Shower

Follow the manufacturer’s instructions for your shower kit. If going curbless, be aware of added complexity.

Tips:

• For slab subfloors, you may need a concrete contractor

• For wood subfloors, you’ll need a permit to notch joists

• Always use a level to ensure the pan is set properly

7. Clean Up and Enjoy

Don’t let debris ruin your new bathroom! Keep a dumpster on hand for drywall, tile, and tub disposal. It’s faster than waiting for your city’s bulk pickup day.

Ready to take your bathroom to the next level? A walk-in shower adds modern luxury, increases accessibility, and boosts value — all with a little DIY spirit.
