Tub-to-Shower Conversion: What Homeowners Should Know

Quick Answer: Is a Tub-to-Shower Conversion Worth It?

A tub-to-shower conversion replaces an underutilized bathtub with a spacious, walk-in shower enclosure. For the vast majority of homeowners, this upgrade is well worth it. It dramatically improves daily accessibility, updates an outdated bathroom aesthetic, and creates a more luxurious, functional space by swapping a cramped tub for a sleek, open shower.

What Is a Tub-to-Shower Conversion?

Removing the existing tub

Adjusting plumbing and drain location

Building a waterproof shower system

The process goes far beyond simply lifting out an old porcelain or fiberglass tub shell. It involves demolishing the surrounding surround, shifting or expanding the drain (since bathtubs typically require a 1.5-inch drain while modern walk-in showers require a 2-inch drain), rebuilding the subfloor slope, and installing a robust waterproof tile or pan system.

Benefits of Converting a Tub-to-Shower Conversion

Easier access

More usable shower space

Modern bathroom design

Better daily function

Bathtubs are frequently left untouched for months in secondary guest baths or primary suites where homeowners prefer quick, invigorating showers over long soaking sessions. Converting a tub eliminates the high, awkward step-over threshold, making the space safer and more accessible for aging-in-place or daily family routines.

What to Plan Before Starting

Shower size

Tile and waterproofing

Glass doors

Niche and storage

Ventilation and lighting

Transforming your footprint requires locking in structural details early. Consider whether you want a full glass enclosure, custom recessed niches for storage, or upgraded recessed lighting and ventilation fans to handle steam.

Why waterproofing matters

Inspection and code considerations

  • Permit Compliance: Because tub-to-shower conversions involve altering plumbing drain lines and electrical or ventilation systems, municipal permits are almost always required—learn more in our guide on Do You Need a Permit to Remodel a Bathroom.
  • Waterproofing Integrity: Shifting from an enclosed tub to an open shower pan makes multi-layered waterproofing critical to prevent subfloor leaks.
  • Planning Checklist: Confirm your drain dimensions, check water heater capacity, select your tile style, and finalize glass door specifications before demolition begins.

FAQ

Is a tub-to-shower conversion worth it?

Yes, especially if you rarely use your bathtub. It improves daily usability, enhances safety, and gives your bathroom a modern, high-end feel.

Do I need a permit for a tub-to-shower conversion?

In most municipalities, yes. Because these conversions require changing plumbing drain sizes and pipe layouts, structural inspections and permits are typically required to meet local building codes.

How long does a tub-to-shower conversion take?

A typical tub-to-shower conversion takes anywhere from 1 to 3 weeks, depending on the complexity of the plumbing modifications, custom tile work, and curing times for waterproofing membranes.

Does removing a bathtub hurt resale value?

Generally, no, as long as your home retains at least one full bathtub elsewhere (such as in a secondary family bathroom). For primary master suites, buyers overwhelmingly prefer large, luxurious walk-in showers over unused soaking tubs.
