Bathroom Remodeling

A lot of South Bay houses were built with one bathroom for the whole family, and plenty of them still have one. We rebuild what is there and, where the plan allows, add the second one.

The hall bath in a postwar tract house in San Jose, Sunnyvale or Santa Clara is usually five feet wide, with a tub, a small vanity and a fan that never did much. It serves three bedrooms, which is fine until it is not. Most calls we get are one of two jobs: gut that hall bath and make it work properly, or carve a second bathroom out of a closet, the end of a hallway, or the back corner of the garage. The second one is a plumbing question first — where the existing drain line runs, and whether the slab or the crawlspace lets us reach it. We answer that before anyone starts picking tile.

Slab houses and Eichlers need care. Radiant tubing in an Eichler slab means saw cuts for new drain lines get located and planned, never guessed at. Older homes in Naglee Park, Willow Glen and the Los Gatos Almond Grove often still have cast iron waste lines and galvanized supply, and once a wall is open that is the moment to replace them rather than tile over them. Venting matters too — a bath fan ducted through to the outside, not dumped into an attic or a soffit. When the vanity opening is an odd width, which in these houses it usually is, we build the vanity in our shop to fit it.

What’s included

  • Demo down to the studs, with the framing and subfloor inspected while it is open
  • Drain, waste and vent reworked to suit the new fixture layout
  • Shower pans and waterproofing built as a full system, not a rolled-on coating
  • Custom vanities, medicine cabinets and linen storage built in our shop to the exact opening
  • Tile setting, including curbless entries where the floor structure will take it
  • Exhaust fan ducted through to the exterior
  • Bathroom electrical brought up to current requirements, including GFCI protection and proper lighting
  • Replacement of galvanized supply and cast iron waste lines found in the walls of older homes
  • Permit drawings and inspections whenever the work goes past a like-for-like swap

Why R Twyns Construction

We are a family-run licensed general contracting and remodeling company (CSLB #896811), building in the South Bay since 2007. Tim Reynolds owns the company and his VP Ben runs the work, so the people who price your job are the people who are on it. The cabinets and finish carpentry come out of our own shop, which is what an older house needs when nothing in it is square. And we tell you what a job actually involves before you commit to it — the load-bearing wall, the drain line, the permit — rather than after the walls are open.

Comprehensive Bathroom Remodeling Service Capabilities

Can we add a second bathroom to a three-bed, one-bath ranch?
Often, yes. The usual spots are a bedroom closet, the end of the hall, or the wall the garage shares with the house. What decides it is how far the new fixtures sit from the existing drain and vent, and whether we are working over a crawlspace or through a slab. We measure and tell you what is workable before you spend money on drawings.
Do we need a permit for a bathroom remodel?
If you are only swapping finishes, often not. Once you move plumbing, change the layout, alter framing or add a bathroom, yes, and we pull it. Ask any contractor for their license number before you let them pull a permit in your name — ours is CSLB #896811, and looking it up takes two minutes. Skipping the permit becomes your problem when you sell.
Our house is an Eichler on a radiant slab. Can you touch it?
Yes, carefully. We locate the tubing before any saw cut, and we lay out the fixtures to keep cutting to a minimum. If the radiant system is still the heat source for the house, protecting it is part of the scope, not an afterthought.
Can you do a curbless shower?
Sometimes. It depends on the floor structure. Over a crawlspace we can usually drop the framing to get the slope we need. On a slab it means cutting and recessing, which is a bigger job and not always the right call. We will tell you which situation your house is in rather than promising it up front.
How do we live here if it is our only bathroom?
We plan for it. That means sequencing the work so the room is out of service for as short a stretch as possible, containing the dust, and being honest with you at the start about the days you will need another option. It is the part of a one-bath remodel people underestimate.
