Tub-to-Shower Conversions: How to Replace a Bathtub with a Walk-In Shower

Tub to Shower Conversion: Turn Your Existing Tub Into a Modern Walk-In Shower

Converting a bathtub to a walk-in shower is one of the most popular home improvement projects homeowners take on today. Whether you want easier access, a modern look, or simply more room in a cramped bathroom, Get a Reno helps you plan and execute a tub-to-shower conversion that fits your life and budget.

Fast Overview: Is a Tub-to-Shower Conversion Right for You?

Research shows that 58% of homeowners prefer a walk-in shower over a bathtub, and it's easy to see why. Filling a bathtub can consume up to 70 gallons of water, while a quick shower uses around 25 gallons. Showers generally require less maintenance and cleaning compared to bathtubs, and removing a bulky tub can make a small bathroom feel larger and more modern.

Key benefits of a shower conversion:

• Improved accessibility and safer entry for all ages

• Less scrubbing and easier daily cleaning

• Updated style that appeals to prospective buyers

• A tub to shower conversion increases home resale value

Who this guide is for:

• Homeowners aging in place or with limited mobility

• Families who rarely use the bath and want to save time

• Small bathrooms where you need the shower space to feel open

• Anyone renovating to upgrade a dated full bath

A typical conversion keeps the same footprint as your existing bathtub-around 60 inches by 30–32 inches-so the installation works in most standard layouts. Get a Reno can connect you with vetted professionals or support you in planning an affordable, DIY-friendly remodeling project.

Planning Your Tub to Shower Conversion

Planning before demolition is the easiest way to avoid budget surprises. Unexpected hidden damage often occurs during tub removal, leading to increased budgets for subfloor repair, mold remediation, or plumbing changes.

Assess your existing tub area:

• Measure length, width, and ceiling height

• Note window placement and current drain location

• Identify whether this is your only tub in the house

It is generally recommended to keep at least one bathtub in a home for resale value. Removing the only tub may lower your home's resale appeal, since homes with bathtubs generally sell for more money. If you have a second full bath with a shower tub combo, you're in a stronger position to convert.

Layout decisions: You can install a standard shower stall in the existing footprint, or expand into adjacent space for a larger walk in shower if the room allows. Note that standard tub drains are 1.5 inches while showers typically require a 2-inch pipe, so plan for drain adjustments.

Local building codes often suggest minimum shower floor areas of 30 × 30 inches, or ideally 36 × 36 inches. Check door swing clearances, ventilation requirements, and GFCI outlets before you decide to start. Create a simple sketch to map your new shower layout, including niches, a bench, and the glass door or curtain line.

Get a Reno can help review your plan and flag common mistakes before work begins.

Design Choices: From Shower Pan to Tile Shower Walls

Balancing style and function is critical here-choosing style over function can lead to dissatisfaction, so prioritize practical shower fixtures alongside aesthetics.

Shower pan options:

• Prefab acrylic or fiberglass base: Fast to install, lower cost, but limited drain positioning. A single stall shower can be as small as 32 inches by 32 inches.

• Custom tile shower pan: Design freedom with linear drains and tile matching your bathroom floor, but requires skilled labor and careful grout maintenance.

Shower wall choices:

• Solid panels (acrylic, solid surface): Fewer grout lines, easier cleaning, quicker installation

• Tiled walls (ceramic, porcelain, stone): Nearly infinite style options; tile costs for showers range from $2 to $45 per square foot depending on materials you purchase

Curbed vs. curbless: Walk-in or curbless showers reduce slip-and-fall hazards compared to high tub walls. A low-threshold curb is a good compromise if full curbless waterproofing feels complex for your project.

Enclosure options: Custom glass shower doors come in various sizes and styles-framed, frameless, or sliding to suit tight spaces. A shower curtain works for simpler, more affordable setups.

Built-in features: Add recessed niches, corner shelves, grab bars, and a fold-down bench for comfort and safety. Walk-in showers can be customized in various styles, and walk-in showers can feature slip-resistant flooring options for added security. Don't forget accessories like a handheld shower head on a slide bar.

Pick finishes that coordinate with the rest of your bath-faucet finish, vanity hardware, and floor tile create a cohesive look. Get a Reno can help you shop and compare materials so you find products that suit your budget.

Cost of a Tub to Shower Conversion

Here's where realistic numbers matter. Standard shower conversion kits range from $200 to $2,000, making them a solid entry point. DIY tub-to-shower conversions typically cost between $1,000 and $3,000, while professional tub-to-shower conversions range from $1,200 to $8,000 depending on scope.

Major cost drivers:

Keeping the drain and water supply lines in roughly the same place is an excellent way to control the price. Re-routing plumbing through joists or a concrete slab adds labor and money fast.

Example comparison: A simple acrylic shower stall using the existing tub footprint might run $1,500–$3,500 total, while a custom tile walk in shower with a frameless glass door, linear drain, and premium fixtures could reach $8,000 or more.

Hidden costs are common-repairing subfloor damage, upgrading waterproofing, or bringing older wiring up to code. Get a Reno recommends gathering multiple written quotes with detailed line items so you can compare the real price. Budget a 10–15% contingency for surprises, and ask about financing options some contractors provide. A smart plan keeps you from spending more money than necessary.

Step‑by‑Step Overview: From Existing Tub to New Walk In Shower

This is a high-level process overview to help you understand what your contractor will do at each phase-not a DIY installation manual. Converting a tub to a shower is a popular home renovation, and knowing the steps helps you hold the job to a high standard.

Preparation: Protect adjacent flooring and finishes with drop cloths. Shut off the water supply, cap fixtures, and set up dust barriers if the rest of the house is occupied.

Demolition: Remove the old shower wall surround or tile as part of replacing the bathtub with a shower, then take out the existing tub. Inspect the framing and subfloor for rot or mold. Dispose of debris responsibly-cast-iron tubs are heavy and may require special hauling.

Rough-in work: Adjust or replace the drain (remember the 1.5-inch to 2-inch upgrade). Confirm correct slope toward the drain, relocate or replace the mixing valve, and add blocking in studs for grab bars or glass door hardware.

Building the base: Install a prefab shower pan or construct a mortar bed with a water tight membrane. Proper waterproofing is critical to prevent leaks, mold, and structural water damage. This step is the foundation of your new shower-don't rush it.

Wall work: Install cement board or approved backer, apply waterproofing, then set tile or mount shower wall panels. Allow adequate drying and curing time between layers.

Finishing touches: Apply grout and seal where needed. Install the shower head, controls, and any additional shower heads or a handheld unit. Hang the glass door or curtain rod, add trim, caulk critical joints where the wall meets the pan, and test the complete shower system for leaks.

Get a Reno encourages homeowners to review each phase and ask for photos of hidden work-waterproofing, framing, and drain slope-before it gets covered.

Timeline, Disruption & Practical Tips for a Smooth Conversion

A straightforward tub-to-shower conversion can often be completed in 2–5 days, and with a specialized crew putting in a prefab unit, it can be completed in as little as 24 hours. Custom tile walk in showers with staging and drying times typically take a full week or longer.

Daily disruption includes: limited bathroom access (plan to use another toilet and bath if available), noise, dust, and workers moving materials through hallways.

Prep tips:

• Clear the bathroom and nearby rooms of personal items

• Protect high-traffic hallways with floor runners

• Arrange temporary toiletry storage in another room

Inspection and curing notes: Some jurisdictions require plumbing or building inspections after rough-in. Mortar and adhesives may need 24–48 hours before the shower pan can bear weight. Grout should cure before regular use, and caulk typically needs 24–48 hours before running water at full temperature. Showers create more steam than tubs, so confirm you have a properly rated bathroom exhaust fan.

Maintenance: Squeegee glass after each use, clean tile with non-abrasive products, and inspect caulk and grout lines annually to keep everything water tight.

Get a Reno encourages you to get a clear written schedule from your contractor, including what happens if delays occur. This is the perfect solution for staying on track.
