Expert Shower Pan Waterproofing in Riverside, CA

Shower pan waterproofing protects the floor of your shower from the inside out. The waterproof layer sits beneath your tile, sealing the mortar bed, drain collar, corners, and curb. Without it, daily water use pushes moisture into your subfloor and wall framing. That leads to mold, rot, and structural repairs that cost far more than the waterproofing itself. In Riverside, CA, many homes were built on concrete slab foundations. Slab construction changes how water moves beneath a shower floor, making proper slope and sealed penetrations especially important. AR Shower Pans is a local, family-owned, licensed and insured waterproofing service. We work on shower pans in Riverside and across the Inland Empire, Orange County, San Diego County, and the Temecula Valley. If you are planning a tile shower build or replacing a failed pan, call us to get the job done right the first time.

Shower Pan Waterproofing FAQ

Common questions about shower pan waterproofing in Riverside, CA.

Yes, tile alone does not stop water from reaching your subfloor. Shower pan waterproofing creates the sealed barrier that keeps moisture out of the structure beneath your tile.

Corners, the drain collar, and the curb are the most common failure points. These spots require careful sealing during the waterproofing process to prevent water from getting through.

Yes, AR Shower Pans is a licensed and insured waterproofing service. We are also locally and family owned, serving Riverside and the surrounding region.

Yes, shower pan waterproofing works on both slab and wood subfloor construction. Slab homes in the Riverside area still require proper slope and sealed penetrations to direct water to the drain.

Water works into the subfloor and wall framing, causing mold growth, wood rot, and structural damage. Repairing that damage costs significantly more than proper waterproofing from the start.

Yes, we serve homeowners across a wide region including Corona, Temecula, Murrieta, Menifee, Ontario, Yorba Linda, Orange County, San Diego, and more.

Going through two bathroom remodels. We use AR shower pans to hot mop both of our shower enclosures. They arrived on time and worked well with us and were respectful to our contractor. Hard to find good respectful service these days.

These guys were awesome. They were very professional knowledgeable and respectful. They showed up on time and got right down to business. My shower pan came out flawless. I couldn’t be happier with the workmanship and customer service both in the field and in the office. I will be recommending this company to all of my customers, friends and family
