Who This Is For

This guide helps Phoenix homeowners, specifically in neighborhoods like Paradise Valley Village and Maryvale, who are looking to modernize their bathrooms. It is designed for residents interested in converting unused tubs into walk-in showers. It also serves those researching the Arizona Registrar of Contractors licensing rules and available water conservation rebates.

Key Takeaways

  • Shower Shift: The median project request in Phoenix is converting a bathtub into a walk-in shower for better accessibility and resale value.
  • License Law: In Arizona, any remodeling project costing over $1,000 requires a contractor licensed by the ROC.
  • Permit Reality: Moving a drain or water line for a shower conversion always requires a city plumbing permit.
  • Rebate Money: The City of Phoenix offers $75 rebates for installing WaterSense toilets with a flow rate of 1.28 gallons per flush.

The era of the oversized garden tub is ending in the Valley of the Sun. Homeowners searching for bathroom remodeling contractors in Phoenix are increasingly trading dusty and unused bathtubs for spacious walk-in showers. Whether you are updating a master suite in Paradise Valley Village or making a home in Maryvale safer for aging parents, the focus has shifted from soaking to accessibility and speed.

However, the construction landscape in Arizona is strictly regulated. You need more than just a handyman with a truck. You need a professional who carries the correct credentials from the Registrar of Contractors. You also need someone who understands local plumbing permits and water conservation incentives.

The Tub-to-Shower Trend

The concept of the bathroom has undergone significant changes. It is no longer just a utility room. It is a space for aging in place and modern design. Mr. Remodel data indicates that 56% of local renovation requests are specifically for tub-to-shower conversions.

Why the Shift?

Phoenix homeowners are prioritizing functionality.

  • Safety: Stepping over a high tub wall is a tripping hazard. Curbless showers eliminate this risk.
  • Space: Removing a bulky tub opens up the room. It often creates enough space for a double vanity or a linen closet.
  • Resale: Modern buyers prefer a large glass-enclosed shower in the master suite over a tub they will never use.

The Fast-Track Design Strategy

Speed is often a priority. About 41% of homeowners want their project to start within seven days. To meet this demand without sacrificing quality, many top-tier contractors offer pre-selected design packages. You can choose from curated palettes like Modern Minimalist or Desert Rustic. This allows you to skip the weeks-long design phase and start construction faster.

The ROC Trust Gap: Knowing Who to Hire

Arizona has some of the strictest contracting laws in the country. This protects you as the homeowner.

The $1,000 Rule

According to the Arizona Registrar of Contractors (ROC), any remodeling project where the total cost of labor and materials exceeds $1,000 requires a licensed contractor.

Hiring an unlicensed entity for a major bathroom remodel is illegal and risky. If the work is poor you have little recourse. You should always verify that your contractor holds a valid license.

  • B-3 License: This covers general remodeling.
  • R-37 License: This is specific to plumbing.

Always ask for the 6-digit ROC number and verify it on the state website before you sign a contract.

Neighborhood Focus: 85032 vs. 85037

Different parts of Phoenix have different remodeling needs. Your zip code often dictates the scope of your project.

Paradise Valley Village (85032): Master Suite Modernization

In this area, homeowners are often updating homes built in the 1980s and 1990s. The goal here is luxury and value. The trend is to remove the cramped shower stall and the massive corner tub. These are replaced with a single expansive wet room or a large glass shower. This often requires moving plumbing lines, which mandates a skilled team.

Maryvale (85037): Safety and Accessibility

In Maryval,e the focus is often on multi-generational living. Families are converting the main hallway bathroom to be safer for older relatives.

For low-income seniors in these areas, financial help is available. The USDA Rural Development program offers Section 504 Home Repair grants. These funds can be used to remove health and safety hazards. Converting a dangerous tub into an accessible shower for a senior often qualifies for this funding.

Permits and Plumbing Codes

There is a misconception that bathroom upgrades are just cosmetic. While changing a faucet is simple, moving a drain is not.

When You Need a Permit

According to the City of Phoenix Planning & Development, you need a plumbing permit whenever you alter the piping system.

If you are converting a tub to a shower, you are moving the drain location. A tub drain is typically 1.5 inches wide, while a shower drain must be 2 inches wide to handle the water flow. This requires breaking the concrete slab and replacing the pipe. This work must be inspected by the city to ensure sewer gases do not leak into your home.

Mr. Remodel connects you with professionals who handle this permitting process. This ensures your home remains code-compliant and protects your resale value.

Water Conservation Rebates

Living in the desert means every drop counts. The City of Phoenix rewards homeowners who choose efficiency.

The $75 Toilet Rebate

If you replace an old toilet with a high-efficiency model, you can get cash back. The City of Phoenix Water Services offers a $75 rebate for installing a WaterSense-labeled toilet.

To qualify the toilet must use 1.28 gallons per flush (GPF) or less. Older toilets can use up to 3.5 gallons per flush. Upgrading saves you money on your water bill and puts cash in your pocket.

Frequently Asked Questions

Do I need a permit to convert my tub to a shower?

Yes. Converting a tub to a shower almost always involves moving the drain and upgrading the pipe size from 1.5 inches to 2 inches. This structural plumbing change requires a permit and inspection from the City of Phoenix.

How do I check if a contractor is licensed in Arizona?

You should visit the Arizona Registrar of Contractors website. Ask the contractor for their 6 digit ROC license number. You can search this number to see if their license is active and if they have any unresolved complaints.

Can I get a grant to fix my bathroom?

If you are a senior citizen aged 62 or older and meet income eligibility requirements, you may qualify for a USDA Section 504 Home Repair grant. This grant can cover the cost of removing safety hazard,s such as installing an accessible shower.

What is the best toilet for water savings in Phoenix?

You should look for a toilet with the EPA WaterSense label. Specifically, you want a model that uses 1.28 gallons per flush or less. Installing this type of toilet can qualify you for a $75 rebate from the City of Phoenix.
