Bathroom Remodeling Plumbing
A bathroom remodel can involve new plumbing behind the walls, especially when you’re changing fixtures or the layout. Moving a toilet six inches might require rerouting a drain line. If you want to add a rain shower, the supply line feeding it might need to be upsized. R&L Plumbing is your bathroom remodeling plumber, and we handle renovations from rough-in through final fixture connections across San Francisco and the East Bay. We work directly with homeowners, contractors, and designers to get it right the first time.
We’ve remodeled bathrooms in San Francisco Victorians with cast iron drains from another century, and in newer East Bay homes where the layout is more flexible. Either way, we plan the plumbing before the tile ever gets ordered.
| Project type | What’s usually involved |
|---|---|
| Refresh (same layout) | Swap fixtures, faucets, and the tub or shower valve |
| Mid-size remodel | New layout for the vanity, toilet, or shower, updated supply and drain lines |
| Full gut remodel | All new plumbing, often replacing old galvanized or cast iron lines |
| Accessibility remodel | Curbless shower, grab bar blocking, raised-height fixtures |
What Does Our Bathroom Remodel Plumbing Cover?
Depending on the scope of your project, our work can include:
- Relocating supply and drain lines for a new layout
- Installing new tubs, showers, toilets, and vanities
- Upgrading old galvanized or cast iron pipe to copper or PEX, or a full repiping if the whole home needs it
- Adding or relocating shutoff valves
- Installing water-efficient, low-flow fixtures
- Rough-in plumbing coordinated with your general contractor's timeline
- Final connections and testing once tile and fixtures are set
Planning Your Remodel Around San Francisco's Older Homes
Many San Francisco homes were built long before today’s plumbing materials and layouts became standard. Sometimes we open a wall and find aging galvanized or cast iron pipes that need attention before the remodel can continue. It’s exactly why we recommend a plumbing walkthrough before demo starts so we can plan for those conditions.
If you’re dealing with a repair rather than changing the bathroom layout, our bathroom plumbing service may be a better fit.
Bathroom remodels in San Francisco may also require permits, depending on the scope of the work. We can help determine what plumbing permits your project needs and coordinate that part of the job before work begins.
What a Bathroom Remodel Typically Involves
Most bathroom remodels start with a walkthrough, then we create a plan for the new layout. During rough-in, we install or relocate supply and drain lines before the walls are closed. Other trades can then complete the tile, drywall, paint, and other finishes.
Once the fixtures are ready to go in, we return for final connections and testing. If you’re already opening walls and updating plumbing, you may also want to consider adding a water filtration system or upgrading your water heater.

It depends on the scope of the project. A fixture refresh may require only a short plumbing visit, while a remodel with a new layout typically includes rough-in work early in the project and final fixture connections near the end.

Often yes, especially if you’re moving fixtures or changing drain lines. We’ll tell you upfront whether your specific project needs a permit and can help coordinate that piece.
