Safer Bathroom in San Mateo: Free In-Home Consultation

The core of a safer bathroom

San Mateo has a large and varied housing stock, and many homeowners want to adapt rather than move. This page outlines how to make a bathroom safer, how the city handles bathroom permits and which local resources are worth a call.

Four features do most of the work: grab bars, a seat, a step-free shower and good lighting. Add a handheld shower and lever handles and the room becomes easier for everyone, including visitors.

Bars are typically placed with the top 33 to 36 inches above the floor. A shower seat sits at 17 to 19 inches. The 2010 ADA Standards set these numbers for public buildings. For a private home they are a guide, not a legal requirement. Our aging-in-place bathroom guide covers each one.

How a curbless shower is built, step by step

Before we design a curbless shower in San Mateo, we look at what is under the bathroom floor: a concrete slab or a wood-framed floor. That decides how the shower area is lowered. Press Play to watch each step, or tap one. Switch between a concrete slab and a wood-framed floor.

How San Mateo handles bathroom permits

The city’s Building Division, (650) 522-7172, reviews bathroom work. San Mateo lists a bathroom or kitchen remodel with wall alterations as eligible for over-the-counter or virtual over-the-counter review when it uses conventional design, needs no structural calculations and needs no Fire Review. Virtual submittals go through the Citizen Self Service portal.

The city’s Bathroom Remodel Guide also sets expectations you can plan for:

  • Tub and shower valves must be pressure-balanced or thermostatic, set to a 120°F maximum.
  • Shower doors must be at least 22 inches wide and open outward.
  • Tub and shower enclosures need safety glazing.
  • Outlets need GFCI protection, and fixtures near water must be rated for damp or wet locations.
  • Interconnected smoke and carbon monoxide alarms are required.
  • Noncompliant fixtures are replaced with water-efficient ones.

The guide cites older code editions, so we always design to the code in effect when the application is filed.

Planning around your house

Each house gets its own answers. We check the floor type before drawing a curbless shower, and we look at how much room is around the toilet. The city guide asks for 30 inches of width at the toilet and 24 inches in front. Accessible layouts usually want more, so we test the plan against a 60-inch turning circle where the room allows it.
