Sunken Tub Remodel With New Tile & Modern Upgrades

Watch the Complete Transformation

See this Phoenix sunken Roman tub transform into a beautiful walk-in shower. This video showcases the tub removal, shower construction, subway tile installation, pebble stone accents, and the 6-function diverter system that creates a spa-like showering experience.

Project Overview

Another Mustache Approved bathroom transformation for a returning client in Phoenix, AZ! For this project, we converted a sunken Roman tub into a beautiful and functional walk-in shower—addressing both the homeowners’ practical needs and their desire for updated, modern aesthetics.

Sunken tubs were popular features in 1980s-1990s luxury homes, but many homeowners find they rarely use them and prefer the convenience of walk-in showers for daily routines. Converting this sunken tub required careful structural work to build up the floor, create proper drainage slopes, and construct a fully waterproofed shower system that would perform flawlessly for decades.

The design features 3×12 white subway tile in a clean straight-lay pattern that creates timeless appeal, paired with flat pebble stone on both the shower pan and niche for spa-like texture and visual contrast. White avalanche grout brightens the entire space while the stainless steel plumbing fixtures with a 6-function diverter system provide ultimate versatility—controlling tub spout, shower head, and handheld sprayer for a luxury showering experience.

The result is a walk-in shower that blends timeless design with everyday comfort and functionality. The homeowners loved it so much they’re having us back soon to remodel their vanity and flooring next—the ultimate compliment for quality work. Ready to convert your own sunken tub?

Why This Design Works for Phoenix Bathrooms

Sunken Roman tubs represent a specific era of home design—they were luxury features in 1980s-1990s construction, often accompanied by surrounding tile decks and garden tub styling. While impressive when new, most homeowners discover they rarely use these tubs for actual bathing, finding them impractical for daily showers and difficult to clean around. Converting these sunken tubs to walk-in showers addresses real functional needs while updating the bathroom’s entire aesthetic.

The structural challenge with sunken tub conversions involves building up the floor to create a proper shower base while maintaining adequate drainage. The sunken area must be filled, framed, and waterproofed correctly to prevent future issues. This requires experienced contractors who understand both the structural requirements and the waterproofing systems necessary for long-term performance—exactly the expertise we bring to every Phoenix Valley project.

Choosing classic 3×12 white subway tile provides timeless appeal that will look appropriate for decades. While tile trends come and go, subway tile has maintained popularity for over a century because of its clean simplicity and versatility. The 3×12 format (wider than traditional 3×6 subway tile) feels more contemporary while maintaining the classic pattern’s proven appeal. The straight-lay installation creates orderly, calming appearance perfect for daily-use showers.

The 6-function diverter system demonstrates how modern plumbing technology can enhance everyday experiences. Rather than choosing between a fixed shower head or handheld sprayer, this system provides both plus tub spout capability—offering ultimate flexibility for different users and uses. The stainless steel finish provides modern styling with exceptional durability, resisting water spots and maintaining appearance with minimal maintenance.

Frequently Asked Questions

Can a sunken tub be converted to a walk-in shower?

Yes! Sunken tub conversions are common bathroom remodels. The process involves removing the tub, building up the sunken floor area to create proper shower base height, installing comprehensive waterproofing systems, and constructing a new shower with tile, fixtures, and drainage. Professional installation ensures structural integrity and long-term performance. Most conversions take 2-3 weeks depending on complexity.

What is a 6-function diverter and do I need one?

A 6-function diverter is a valve system that controls multiple water outlets (shower head, handheld sprayer, tub spout, body jets, etc.). Benefits include ultimate versatility for different users and uses, luxury spa-like experience, independent control of each outlet, and future-proofed plumbing (outlets can be added later). While not essential, these systems significantly enhance daily showering experiences.

Why choose subway tile over other tile patterns?

Subway tile offers proven timeless appeal (popular for over 100 years), versatility across design styles (works with traditional through contemporary), easy maintenance with simple cleaning, and wide availability in many colors and sizes. The 3×12 format provides more contemporary look than traditional 3×6 while maintaining classic pattern’s enduring appeal. It’s a safe choice that won’t look dated.

Should I combine pebble stone with subway tile?

Yes! Combining materials creates visual interest and design sophistication. Pebble stone on the shower pan provides excellent slip resistance and organic texture, while subway tile on walls offers clean, modern appearance. The contrast between smooth tile and natural pebble creates spa-like aesthetic while serving practical purposes—each material in the location where it performs best.
