If you have an old, rarely used garden tub or an outdated alcove bathtub cluttering your bathroom, you are not alone. Across Chandler, Arizona, homeowners are increasingly choosing to convert their old tubs into modern, spacious walk-in showers. This project is one of the most effective ways to optimize bathroom space, improve accessibility, and modernize your home's design.
However, a successful tub-to-shower conversion requires careful planning, budgeting, and technical execution. From navigating City of Chandler building permits to selecting waterproofing systems that withstand the shifting desert soils, there is a lot to consider before demolition starts. In this comprehensive guide, we cover everything you need to know to plan a successful tub-to-shower conversion in your Chandler home.
Why Convert Your Bathtub to a Walk-In Shower?
For many households, the traditional bathtub-shower combination is no longer practical. Tubs can be difficult to step into, hard to clean, and take up valuable square footage. Here are the primary reasons Chandler homeowners are making the switch:
- Enhanced Spatial Efficiency: A standard alcove bathtub occupies a footprint of 30 inches by 60 inches. By replacing this tub with a walk-in shower, you instantly gain a spacious, open showering area. If you remove a larger corner garden tub, you can create a luxury double shower or gain enough room to install a double vanity.
- Improved Safety and Accessibility: Stepping over a 15-inch tub wall can be a slipping hazard, particularly for seniors or individuals with limited mobility. A walk-in shower with a low-profile curb (or a zero-threshold curbless entry) offers a much safer transition. This is highly popular in active adult communities like Sun Lakes, where universal design is a priority.
- Elevated Modern Aesthetics: Replacing an acrylic tub surround with custom porcelain tile, frameless glass panels, and modern fixtures instantly upgrades your bathroom from standard builder-grade to a spa-like retreat.
- Reduced Cleaning and Maintenance:Acrylic tubs tend to yellow, scratch, and collect soap scum over time. A modern tiled shower with resin-based epoxy grout is much easier to maintain, especially when dealing with the heavy mineral content of Chandler's municipal water supply.

Technical and Code Requirements for Chandler Conversions
Converting a tub to a shower is not a simple cosmetic swap. It involves critical plumbing and structural adjustments that must comply with local building codes.
1. Expanding the Drain Line (The 2-Inch Rule)
Under the International Residential Code (IRC) enforced by the City of Chandler, a bathtub is allowed to drain through a 1.5-inch pipe. However, a shower requires a minimum 2-inch drain pipe to prevent water from backing up and overflowing. During demolition, a professional specialist must saw-cut the concrete slab (or access the subfloor) to expand the drain line and trap to 2 inches. Attempting to drain a shower through a 1.5-inch tub drain is a code violation and a recipe for standing water.
2. Relocating and Upgrading Valves
Bathtub valves are set lower (around 12 to 15 inches from the tub floor) than shower valves (typically 45 to 48 inches). A conversion requires extending the copper or PEX supply lines upward. This is also the perfect time to replace your old mixing valve with a pressure-balancing shower valve to prevent sudden temperature drops when someone flushes a toilet elsewhere in the house.
3. Shower Pan Slope and Waterproofing
To prevent leaks, a shower floor must slope toward the drain at a rate of 1/4 inch per foot. The substrate must be completely waterproofed. Traditional cement board and plastic sheeting are prone to mold and leaks. At ARZ Home Remodeling, we use the advanced Schluter-KERDI waterproofing systemon all custom shower builds. The bonded sheet membrane creates a vapor-tight seal, protecting your home's framing from dry rot and water damage.
Designing for Chandler's Hard Water Challenges
Chandler's municipal water is exceptionally hard, averaging 18+ grains of minerals per gallon. When hard water evaporates on shower walls, it leaves behind tough calcium scale. Protect your investment by designing with these materials in mind:
- Epoxy Grout: Upgrade from cement-based grout to resin-based epoxy grout. It is non-porous and waterproof, preventing hard water minerals from staining your grout lines. Learn more about our tiling methods in our bathroom tile installation guide.
- Large-Format Porcelain Tile:Porcelain is extremely dense and absorbs almost no water. Large-format tiles (like 12" x 24" or 24" x 24") minimize the number of grout lines you have to scrub.
- Hydrophobic Glass Coating: Ensure your frameless shower glass has a factory-applied hydrophobic coating to repel water and prevent clouding. Read more about glass choices in our guide: is frameless shower glass worth it in Chandler.
Remodeling Team Vetting Checklist
Hiring the right team is the single most important decision you will make for your project. A poorly installed shower pan can leak behind your walls, causing thousands of dollars in structural damage before you notice it. Use this checklist to vet your remodeling specialists:
- ✓Active Arizona License: Ensure the team holds an active license with the Arizona Registrar of Contractors. Unlicensed handymen cannot legally perform plumbing modifications or pull city permits. ARZ Home Remodeling is professional under .
- ✓Comprehensive Insurance Coverage:Ask for proof of general liability and workers' compensation insurance to protect your property and workers on site.
- ✓City Permits and Inspections: Verify that the team will submit plans and pull the required plumbing and building permits through the City of Chandler Development Services Dept(located at 215 E Buffalo St). Never pull permits yourself as an "owner-builder."
- ✓Waterproofing Standards: Confirm they use a modern waterproofing system (like Schluter-KERDI) rather than outdated methods.
- ✓Detailed, Fixed-Price Contract: Do not accept vague estimates. Insist on an itemized contract listing exact materials, labor, and a clear payment schedule tied to construction milestones.
- ✓Written Workmanship Warranty: Choose a remodeling team who stands behind their work. We back all of our custom bathroom renovations with a 2-year written workmanship warranty.
5 Frequently Asked Questions (People Also Ask)
1. Will removing my bathtub hurt my home's resale value?
As long as your home retains at least one bathtub (typically in a guest or hall bathroom), converting an underutilized tub into a custom walk-in shower will not hurt your resale value. In fact, replacing an old garden tub in the master suite with a large, luxury walk-in shower is highly sought after by modern homebuyers and typically yields a strong return on investment.
2. How long does a tub-to-shower conversion take?
A standard alcove tub-to-shower conversion takes between 5 to 10 working days. This includes demolition, plumbing rough-in, city inspections, waterproofing, tile setting, grouting, and installing glass panels. A luxury curbless master conversion with layout changes can take 2 to 3 weeks. You can review a typical day-by-day breakdown in our bathroom remodeling timeline guide.
3. Can I convert a tub to a shower without tearing out the walls?
No, a professional tub-to-shower conversion requires removing the wall materials surrounding the tub down to the bare wood studs. This is necessary to access and adjust the plumbing valves, expand the drain line, inspect the framing for water damage or dry rot, and install a continuous, leak-proof waterproofing barrier.
4. What is the difference between a curbed and a curbless walk-in shower?
A curbed shower has a raised threshold (usually 3 to 5 inches high) that holds water inside the shower pan. A curbless shower has a flush, flat entry with no threshold, requiring the subfloor to be recessed and sloped toward a high-capacity drain. Curbless entries provide seamless aesthetics and excellent accessibility for aging-in-place but require more labor and structural modification.
5. Do I need to get HOA approval for a bathroom remodel in Chandler?
If you are only remodeling the interior of your home, you do not need architectural approval from your Homeowners Association (HOA). However, many master-planned communities in Chandler (like Fulton Ranch, Ocotillo, and Warner Ranch) have strict regulations regarding construction dumpsters, working hours, and crew parking. Your remodeling team must coordinate with these rules to avoid fines.
