San Francisco service · Since 1929
Toilet, bidet & fixture plumbing, repair to luxury installation.
We repair, replace, and install standard and smart toilets, bidets, faucets, sinks, disposals, tubs, showers, and in-wall valves across San Francisco. For premium fixtures, our shared Lutz Bath & Kitchen showroom adds factory training, certified parts access, and direct manufacturer support.
Quick answer
One plumber for a running toilet, leaking faucet, smart bidet, or full fixture replacement.
Lutz Plumbing repairs and installs toilets, bidets, faucets, sinks, disposals, tubs, showers, and in-wall valves in San Francisco. For a standard repair or swap, we inspect the fixture and every connection that keeps it watertight. For a smart toilet or designer fixture, we also verify the rough-in, clearances, water pressure, electrical needs, proprietary parts, and manufacturer commissioning steps before calling the job complete.
If water is actively leaking at the floor, wall, supply, or cabinet, close the fixture shutoff if it is safe to reach and call us. A visible leak can involve the connection behind the fixture, not just the fixture itself.
What to send with your request
- A photo of the full fixture and the leak or failed part
- Brand and model number, especially for TOTO, smart toilets, and designer faucets
- Whether the fixture is being repaired, replaced, or newly added
- Any known floor, wall, electrical, shutoff, or access constraint
Why owners, designers, and architects hire us
Single-point accountability, specification to commissioning.
No other plumbing company in San Francisco owns dealer, trainer, and installer under one roof. That's the structural reason warranty claims, certified parts, and factory tech support move faster with us than with anyone else.
Direct from the manufacturer
Because Lutz Bath & Kitchen is a direct-buy dealer for these lines, we source fixtures and certified replacement parts factory-direct, not from a supply house. Faster access to genuine parts, warranty-compliant service, and zero third-party disputes when something needs a call to the manufacturer.
Factory-trained installers
Our technicians train directly with the manufacturers we install: angle-stop tolerances, proprietary rough-in valves, concealed-cartridge service, and the quirks each brand has that a generalist plumber hasn't seen. We are the only Factory-Trained Authorized Service Representative (ASR) for TOTO in San Francisco.
Showroom under the same roof
Spec your project at Lutz Bath & Kitchen on 17th Street, see and touch the fixtures, and have the same family install them. Showroom and plumbing shop share one building, one relationship, one point of accountability, no lost specs between showroom, contractor, and installer.

Repair, replace, or rework
The fixture is only one part of the decision.
We price the actual plumbing scope after checking the connections, access, and compatibility around the fixture. These are the factors that change the work.
When repair is worth considering
A serviceable fill or flush valve, supply connection, seal, mounting issue, faucet cartridge, or supported smart-fixture component can often be corrected without replacing the whole fixture. We identify the failed part and confirm that the body, rough-in, and surrounding connection are sound before recommending repair.
When replacement is the practical path
Cracked porcelain, a damaged or badly corroded mounting surface, an unsupported proprietary fixture, repeated failures, or an incompatible rough-in can make another repair a poor investment. Replacement is also the right time to correct a weak shutoff, flange, supply, or drain connection instead of hiding it behind a new fixture.
What changes the price
Why it matters for luxury fixtures
Preventing the three most common luxury fixture failures.
A high-end shower system and a builder-grade valve take about the same amount of time to install. The difference is whether the installer knows the in-wall rough-in spec, has the certified cartridge on the truck, and can call the factory directly when something is off. Most plumbers don't, and the customer finds out at drywall-close.
We built the Lutz Plumbing and Lutz Bath & Kitchen pairing to close that gap. The showroom spec, the installation crew, and the factory relationship are all the same family.
Brands we install and service
Dealer-direct with the specification lines you're using.
Through Lutz Bath & Kitchen, we carry and install more than 80 curated luxury lines. These are the ones most commonly specified on San Francisco projects.
European architectural
Certified installation and in-wall rough-in for German, Italian, and Danish design houses with proprietary valves, metric threads, and tight warranty terms.
Japanese & smart toilet
Factory-trained installation and authorized service for precision toilets and bidet seats. Lutz Plumbing is San Francisco's only Factory-Trained Authorized Service Representative (ASR) for TOTO.
Kitchen & bath classics
Spec-compliant installation of American and British heritage lines that still draw designer specs for traditional and transitional SF projects.
Showers, sinks, tubs & drains
Installation of luxury shower systems, designer sinks, freestanding tubs, and linear drains, where rough-in precision decides whether the finish install goes clean or gets torn back out.
Wellness & spa
Installation and commissioning of steam, sauna, hydrotherapy, and smart-water systems. Several are demo-active in the LBK showroom under the same roof.
How we install
Specified, roughed-in, commissioned, and warrantied.
The same crew from wall-open to wall-close, and the same phone number for warranty service years later.
Specify with confidence
Work with our showroom or bring your designer's spec. We verify every fixture against the existing or planned rough-in and flag anything that needs re-routed water, electrical, or venting before the wall closes up.
Rough-in, done right
Luxury fixtures are won or lost in the rough-in. We set angle stops, drain centerlines, and in-wall valves to each manufacturer's exact spec. If another trade roughed it in wrong, we tell you now, not after the tile goes up.
Finish install & commissioning
Certified parts, torque-to-spec, and a pressure test on every connection. Smart fixtures are commissioned, paired with your Wi-Fi if applicable, and walked through with you before we leave.
Warranty & service, factory-backed
We handle manufacturer warranty claims for fixtures purchased through our showroom, no searching for receipts or chasing a rep on your own. Because we're direct-dealer, a warranty claim moves through us to the factory, not through a supply house you've never heard from.
Fixture service questions
Answers before you schedule.
The model, rough-in, and condition around the fixture usually determine whether the visit is a repair, a clean swap, or a larger correction.
Do you repair toilets, bidets, and faucets, or only install new fixtures?
We handle repair, replacement, and new installation. Common work includes running-toilet components, supply and seal leaks, flange problems, faucet cartridges, bidet seats, smart toilets, and warranty service for supported fixtures.
Can you install a toilet or faucet I bought somewhere else?
Yes, when the fixture is complete and compatible with the existing rough-in. Send the brand, model, specification sheet, and a photo of the current installation so we can flag missing adapters, valve changes, electrical needs, or clearance problems before the visit.
What needs to be checked before installing a smart toilet or bidet?
We verify the drain rough-in, angle-stop position, water pressure, mounting clearances, and the model's electrical requirements. Many smart toilets need a nearby GFCI-protected receptacle, and the exact circuit requirement depends on the manufacturer and model.
Can you repair a damaged toilet flange or incorrect rough-in?
Yes. We inspect the flange, floor connection, drain centerline, shutoff, and supply before setting the new fixture. If the flange or rough-in needs correction, we explain that scope before the fixture is installed.
Is Lutz Plumbing authorized to service TOTO fixtures in San Francisco?
Yes. Lutz Plumbing is San Francisco's Factory-Trained Authorized Service Representative for TOTO, with access to certified parts and manufacturer support for covered products.
Designers, architects & GCs
A trade partner who knows the spec sheet before you send it.
We work quietly behind the scenes on custom residential projects across San Francisco, the Peninsula, Marin, and the East Bay. If your client is spec'ing a fixture we install, we can review drawings, pre-verify rough-ins, and flag warranty-critical installation notes before ground breaks. Bring us in at schematic, not at punch list.
