Which install are you planning?

Pick the fixture. The steps, the Miami-Dade permit note, and who should lead the job update with your choice. We price the visit after we see the opening, the shutoffs, and whether a wall has to come open.

Sink details

Kitchen hookups add a strainer, and often a disposal or a dishwasher tailpiece.

Permits, as of October 2026

Unincorporated Miami-Dade: a licensed plumbing contractor may replace faucets and sink or lavatory fixtures without a permit. Bathtubs and shower valves are not on that list. Replacing or rearranging valves or pipes is new work under Florida Building Code section 105.2.

City of Miami: like-for-like sink or lavatory replacement, and faucet repair that does not reroute plumbing, are listed as work that does not need a permit. Bathtub change-out and shower-pan change-out are published as Easy Permits, so the city still wants a plumbing permit for those swaps. The city also lists kitchen-sink change-out as an Easy Permit, so confirm with the Building Department when the counter or the drain arm is changing.

House Bill 803, effective July 1, 2026, lets some home projects under $7,500 skip a building permit. Miami-Dade says plumbing is not part of that exemption. The older faucet and sink exemptions above still sit on the county list. Being under $7,500 does not by itself skip a plumbing permit.

Each city in the county has its own building official. Unincorporated property is the county process.

What the visit includes

  1. 1

    Shut the water off and confirm the shutoff valves actually close.

  2. 2

    Match the bowl to the opening: drop-in rim on the counter, or undermount clipped under the stone.

  3. 3

    Set the faucet, strainer or pop-up, trap, and the dishwasher or disposal tailpiece when there is one.

  4. 4

    Fill the bowl, run the disposal or pop-up, and watch the trap for leaks.

Time on site, as of 2026: Angi (updated September 26, 2026) says a professional typically installs a sink in one to four hours, with most routine jobs around one to two hours, and that an undermount or a countertop change can take a full day. HomeGuide (July 14, 2025) says hooking up a new sink and drain with the faucet takes about two hours. Those two agree on a same-opening swap. They do not describe a new stone top.

Plumber or remodeler?

A drop-in in the existing opening is a plumber visit.

Plumber

Set the rim, faucet, drain, and trap. Kitchen jobs add the disposal or dishwasher arm when you already have one.

Remodeler

Not required when the counter opening, cabinet, and drain arm stay put.

Frequently Asked Questions

Common questions about kitchen & bathroom plumbing

How much does bathroom remodel plumbing cost?
Bathroom remodel plumbing starts with a $49 evaluation and upfront pricing before any work. Replacing a fixture in place is a smaller job than moving it or running new rough-in. The quote follows the scope we find on site.
Can you move my bathroom fixtures to new locations?
Yes! We can relocate sinks, toilets, showers, and tubs as part of a remodel. This requires opening walls/floors for new plumbing runs and typically requires permits. We handle all aspects including permits.
Do I need a permit for bathroom plumbing?
It depends on the city and whether pipes move. As of October 2026, unincorporated Miami-Dade lets a licensed plumber replace faucets and sink or lavatory fixtures without a permit. Bathtubs and shower valves are not on that list. The City of Miami lists like-for-like sink replacement and faucet repair that does not reroute plumbing as work without a permit, and lists bathtub and shower-pan change-outs as Easy Permits. House Bill 803, effective July 1, 2026, does not exempt plumbing just because the job is under $7,500. Moving a fixture is a permitted plumbing job. We confirm which building official covers the property before we start.
How long does bathroom plumbing take?
As of 2026, national guides put a standard faucet at about one to two hours (Angi, updated July 8, 2026; HomeGuide, July 14, 2025; This Old House, updated June 6, 2026). Angi (updated September 26, 2026) says a routine sink install is often one to two hours, and an undermount or new counter can take a day. Angi (updated July 9, 2026) and HomeGuide (August 20, 2025) both say a professional bathtub replacement typically takes one to three days. Moving pipes or rebuilding the surround is scheduled with the other trades. These are national planning ranges, not a Miami quote.
Can you install a new bathroom in my home?
Yes! Adding a bathroom requires planning for drain and vent connections, water supply, and proper ventilation. We can assess feasibility, provide estimates, and handle all plumbing from rough-in to final fixtures.
Do you work with general contractors?
Absolutely! We regularly work with GCs, designers, and homeowners on remodel projects. We coordinate scheduling with other trades and can attend planning meetings to help with plumbing decisions.
What toilet brands do you recommend?
We install all major brands. For reliability and value, we often recommend Kohler, American Standard, and TOTO. We can help you choose based on your budget, style preferences, and water efficiency goals.
Can you help me select fixtures?
Yes! While we install whatever fixtures you choose, we're happy to make recommendations based on your needs, budget, and style. We can also identify compatibility issues before purchase.
What is the difference between undermount and drop-in sink installation?
A drop-in sink has a rim that sits on the counter, so it can go into an existing cutout, including laminate. An undermount bowl hangs under a stone or solid-surface top. The counter shop usually cuts the opening and clips the bowl. We connect the faucet, drain, trap, and any disposal or dishwasher arm. Moving either style to a new cabinet is a different job from a same-opening swap.
Is bathtub installation a plumber job or a remodeler job?
If the tub stays in the same alcove and the surround stays closed, a plumber can set the tub, drain, and valve. If the tile comes off, a remodeler leads demolition, waterproofing, and the new wall, and the plumber sets the tub and shower valve before that wall closes. Moving the tub needs both. The 2023 Florida Building Code requires the tub or shower valve to limit hot water to 120°F.
