The five parts hidden behind the tile
Every shower has the same five systems, even when the finish looks very different. Hot and cold supply pipes feed a valve in the wall. The valve blends them and sends water up a pipe to the shower arm. Spent water falls into a drain, passes through a trap, and joins the home's waste line, which is vented to the roof or an air admittance device.
Knowing which part you are looking at tells you whether a job is cosmetic or structural. The table sorts the common ones.
| Part | What it does | Common fault | Who should do the work |
|---|---|---|---|
| Showerhead and arm | Delivers the spray | Mineral clogging, loose threads, small drip at the wall | Homeowner, with plumber tape on the threads |
| Trim kit and handle | Covers the valve and sets temperature | Loose handle, cracked cap | Homeowner |
| Valve cartridge | Mixes hot and cold in the wall | Drip from the spout, temperature swings | Homeowner if there are stop valves, otherwise a plumber |
| Rough-in valve body | Connects to the supply pipes | Leak behind the tile, wrong depth | Licensed plumbing contractor |
| Drain and trap | Takes water away and blocks sewer gas | Slow drain, gurgling, sewer smell | Plumber for anything below the strainer |
| Vent line | Lets air into the drain so water flows | Gurgling, drained trap | Licensed plumbing contractor |
Drain, trap and slope: the part that cannot be wrong
The trap is a curved section of pipe that holds a few inches of water. That water seal stops sewer gas from rising through the drain. A standard shower normally uses a 2-inch drain and trap, and your inspector will confirm the exact size for your fixture.
Slope matters as much as size. The model code behind Florida's rules calls for small horizontal drain pipes to fall about 1/4 inch per foot toward the sewer. Too flat and solids settle, too steep and water outruns the solids. The shower floor itself also has to slope to the drain, usually checked with a flood test before tile goes down.
What Dania Beach Homeowners Should Know Before Remodeling
Dania Beach housing is not mostly single-family. Census ACS data lists 16,348 housing units, and only 21.7 percent are detached single-family homes. Many showers sit in condos and apartments, so building rules and association approvals may apply on top of the city permit.
The city's Building Division sits under Community Development and runs an online permit portal, plus pages for permits, inspections and the application process. Start there before you hire anyone. Its address and phone were not on the pages we could read, so look them up on the city site.
The median home was built in 1977, which means shower valves and drains behind the tile are often original. Expect surprises when a wall opens. Owners in Davie or West Park should ask their own building office which rules apply, because Dania Beach's portal covers only Dania Beach.

Why a shower gurgles or smells
Gurgling usually means air cannot get into the line behind the water. A blocked or missing vent pulls water out of the trap, and the sewer smell follows. Slow drains with no vent problem point to hair and soap in the trap itself.
Try a plunger and a hair catcher first. If bubbles come up in a nearby toilet or sink, the blockage is farther down and a drain machine or camera is the right tool. Our drain cleaning crews handle that, and a sewer camera inspection shows what the pipe looks like inside.
What Florida requires for shower plumbing work
Florida's plumbing rules follow the Florida Building Code, Plumbing (8th Edition, 2023, based on the 2021 International Plumbing Code, IPC). That edition took effect on December 31, 2023, and a newer edition is in development, so ask the Building Division which one applies on the day you apply.
Permit rules vary, so ask the Dania Beach Building Division before you move a shower valve, relocate a drain or replace concealed pipe.
Licensed contractor rules for the work itself
Under Florida Statutes section 489.105, a plumbing contractor is one whose services are unlimited in the plumbing trade. Section 489.127 makes it unlawful to act as a contractor without the required licence or to start permit-required work before the permit is in effect. Section 489.128 says contracts with an unlicensed contractor are generally unenforceable.
Anyone can check a licence for free on the Florida DBPR Licensee Search at myfloridalicense.com. Look up the name, confirm the licence type, and read the permit number off the job posting. If a contractor suggests skipping the permit, treat that as a reason to walk away.
What to check before you start a shower project
Some of the work is fair game for a careful owner. These points keep a small job small and flag the moment it stops being small.
- Confirm the project is only a trim, showerhead or cartridge swap, with no pipe moved
- Locate the water shutoff for the bathroom or the main, and test that it closes
- Look for an access panel behind the valve, often in the next room or closet
- Check the ceiling below for stains, since a slow leak can hide for months
- Ask your condo or HOA board about approval rules if you share walls with neighbors
- Call the Building Division before you open a wall or touch a drain
What a homeowner should not do
Leave the rough-in to a licensed plumbing contractor. That covers soldering or crimping supply lines inside a wall, setting the drain height, building the trap arm and venting, and tying new work into the existing waste line. Mistakes there do not show until the tile is finished, and fixing them means demolition.
Cost figures show why. Angi's 2026 guide puts a shower rough-in at about $1,500 to $3,500 and a whole-bathroom rough-in at $3,000 to $20,000, and Florida prices vary. For a shower that already leaks, our plumbing installation team and leak detection service can tell you whether the valve or the pan is at fault. Call Call (954) 697-4920 to talk it through.
Frequently Asked Questions
Do I need a permit to replace a showerhead or shower valve trim in Dania Beach?
A showerhead or trim swap that moves no pipe is generally minor, but exemption rules are narrow. Replacing the valve body inside the wall or moving the drain is a different case. Ask the City of Dania Beach Building Division before you start.
Can a handyman install a new shower drain in Florida?
Not if the work needs a permit. Florida law requires a licensed contractor for permit-required plumbing and makes unlicensed contracting unlawful. Check any name on the DBPR Licensee Search.
Why does my shower drain gurgle when the washer runs?
Both fixtures often share a vent or a branch line, so a blocked vent or partial clog shows up in each. Gurgling means air is fighting the water. Stop and have the line checked if it happens often.
What slope does a shower drain pipe need?
The model code behind Florida's rules asks for about 1/4 inch of fall per foot on small horizontal drains. Your inspector confirms the exact figure for your job. Do not guess, because flat pipe clogs.
Is a shower in a Dania Beach condo treated differently?
Often yes. A unit shares walls and stacks with neighbors, so the association may require approval and a licensed contractor even for work the city would allow. Read your documents first. For an urgent leak, call Call (954) 697-4920.
Code reference: plumbing work in Florida falls under the Florida Building Code, Plumbing (8th Edition, 2023), which is based on the 2021 International Plumbing Code (IPC). Ask the Dania Beach Building Division whether your job needs a permit.
