Bathroom Plumbing Services We Provide
From a toilet swap to a full custom shower system — we handle every bathroom plumbing need.
Toilet Installation & Replacement
All styles including comfort height (17–19 in.) and dual-flush models. Wax ring, supply line, and shutoff valve included. Old toilet hauled away.
Vanity & Sink Installation
Undermount, vessel, and pedestal sinks. Single and double vanities. Drain, P-trap, supply lines, and shutoff valves — all installed correctly.
Shower Valve & Trim Installation
Pressure-balancing valves (code required) and thermostatic valves for precise temperature control. All major brands: Kohler, Moen, Delta, Grohe.
Bathtub Installation & Replacement
Alcove, freestanding, and drop-in tubs. Floor-mount faucet rough-in for freestanding tubs. Drain, overflow, and supply connections.
Shower Pan & Tile Work Coordination
We set the drain at the correct location and height for your tile layout. We coordinate with your tile contractor so the slope and drain placement are right before tile goes in.
Bathroom Drain Cleaning
Hair and soap scum are the primary causes of slow bathroom drains. We clear tub, shower, and sink drains and inspect for deeper blockages.
Exhaust Fan Installation
Proper bathroom ventilation prevents mold and moisture damage. We install exhaust fans with correct CFM rating for your bathroom size.
Heated Floor Rough-In Plumbing
We coordinate the plumbing rough-in with heated floor installation — ensuring supply and drain locations don't conflict with heating elements.
Warning Signs You Need Bathroom Plumbing Service
Small bathroom plumbing problems become expensive ones quickly. These signs mean it's time to call.
Toilet that rocks or moves — wax ring failure allows sewer gas and water to leak under the floor
Toilet that runs constantly — flapper or fill valve failure wastes 200 gallons per day
Shower that drips when off — cartridge failure; the drip worsens over time
Low water pressure in the shower only — showerhead clog or valve issue
Slow bathtub drain — hair and soap scum buildup restricting flow
Toilet that requires multiple flushes — partial blockage or low-flow issue
Discolored grout around the toilet base — wax ring leak allowing water under the floor
Mold or mildew on bathroom walls — inadequate ventilation or a hidden leak
What Causes Bathroom Plumbing Problems?
Age & Worn Components
Toilet flappers last 3–5 years. Shower cartridges last 5–15 years. Wax rings can fail after 20–30 years. Regular replacement is normal maintenance — not a sign of poor quality.
Hard Water Mineral Buildup
Southern Maryland well water deposits calcium and magnesium inside shower valves, showerheads, and faucet cartridges. This accelerates wear and causes drips, low pressure, and temperature control issues.
Inadequate Ventilation
Bathrooms without proper exhaust ventilation develop mold and moisture damage behind walls and under floors. A properly sized exhaust fan is essential — especially in bathrooms with showers or tubs.

Scope & Estimate
We walk through the project, identify all plumbing work required, and provide a written estimate. We flag any issues (galvanized lines, wet wall location) before work begins.
Rough-In Plumbing
Drain, supply, and vent lines installed to the correct locations. We provide a rough-in diagram for your tile installer. Inspection scheduled if permits required.
Finish Plumbing
After tile and finish work is complete, we return to set fixtures — toilet, vanity, shower valve trim, tub faucet. All connections made and tested.
Final Test & Walkthrough
Every fixture tested. Water pressure verified. Drain flow confirmed. We walk you through the completed work before we leave.

Common Homeowner Problems
- Old shower valve with poor temperature control
- Tub that's cracked, stained, or outdated
- Toilet in the wrong location for a new layout
- Vanity plumbing that doesn't match new fixture locations
- Shower drain in the wrong position for a new tile layout
- Wanting to add a second bathroom or half bath
- Upgrading to a walk-in shower from a tub/shower combo
- Adding luxury features like body sprayers or rain heads
- Old galvanized supply lines behind walls
- Water pressure issues affecting shower performance
Warning Signs to Watch For
- Shower valve that can't maintain consistent temperature
- Tub or shower showing cracks, chips, or deep staining
- Corroded or leaking supply lines behind walls
- Shower drain that doesn't align with new tile design
- Toilet that rocks or has a soft floor around the base
- Vanity plumbing that leaks or has corroded connections
- Low pressure in shower even with good whole-home pressure
Shower Valve & System Installation
The shower valve is the heart of your shower system. We install pressure-balanced valves (required by code for scald protection), thermostatic valves for precise temperature control, and multi-outlet systems that control body sprayers, rain heads, and handheld sprayers independently. We work with all major brands including Kohler, Moen, Delta, and Grohe, and we install everything to manufacturer specifications so your warranty stays valid.
- Pressure-balanced shower valves (code required)
- Thermostatic valves for precise temperature control
- Multi-outlet shower systems
- Body sprayer installation
- Rain head installation
- Handheld sprayer rough-in
- Diverter valve installation
- All major brands supported
Tub Replacement & Freestanding Tubs
Replacing a tub involves more than just swapping the fixture — it requires disconnecting and reconnecting supply lines, drain, and overflow, and often modifying the surrounding structure. Freestanding tubs add complexity with floor-mounted faucets and exposed supply lines that need to be perfectly positioned. We handle all of it, coordinating with your contractor on timing so the plumbing rough-in is ready when the tile and finish work begins.
- Alcove tub replacement
- Freestanding tub installation
- Floor-mounted tub faucet rough-in
- Tub drain and overflow installation
- Whirlpool and air tub plumbing
- Tub-to-shower conversion
- Supply line replacement behind walls
Toilet Relocation & Vanity Plumbing
Moving a toilet requires relocating the drain, vent, and supply line — which often means opening the floor and sometimes the wall. We handle toilet relocation correctly, including proper venting to prevent odor and gurgling issues. Vanity plumbing includes supply line rough-in, drain rough-in, and finish connections for single and double vanities, vessel sinks, and wall-mounted fixtures.
- Toilet relocation (drain, vent, supply)
- Single and double vanity plumbing
- Vessel sink drain installation
- Wall-mounted faucet rough-in
- Pedestal sink installation
- Drain rough-in for new locations
- Vent pipe modification
Luxury Bathroom Upgrades
A luxury bathroom is only as good as the plumbing behind it. We install the full range of high-end bathroom plumbing features — steam shower systems, heated floor supply connections, smart toilet rough-in, and whole-bathroom water treatment for the best possible water quality at every fixture. We work with your designer or contractor to ensure the plumbing supports your vision.
- Steam shower generator plumbing

"Absolutely blown away by the service from Deep Dive Plumbing Maryland! We had ongoing issues with our well water for years — bad smell, staining, and constant problems with pressure — and nobody ever took the time to truly figure out the root cause. Terry and the team came out, performed a full water analysis, explained everything in detail, and designed a system specifically for our home instead of just trying to sell us random equipment. You can really tell they care about doing things the right way. The install was extremely clean and professional, they walked us through how everything works, and our water has never looked or tasted better. The difference is unbelievable."

"Called Deep Dive after waking up to no water pressure. They were at my house within two hours and had the well pump diagnosed and replaced the same day. Terry walked me through every step and explained exactly what failed and why. Honest pricing, no surprises on the invoice. This is the only plumber I'll call going forward."

"We recently had Deep Dive Plumbing Maryland out to our home in Annapolis after we suddenly started noticing sewer flies throughout the house. They truly lived up to their name and performed a full "deep dive" diagnostic inspection instead of just treating the symptom. During their inspection they discovered our sewer pipe connected to the toilet had been leaking into the basement for quite some time. The team explained everything clearly, provided upfront pricing before starting any work, and even gave us a military discount which was greatly appreciated. They were professional, respectful, extremely knowledgeable, and took the time to make sure the repair was done correctly."

"We had a mystery leak in our bathroom and everyone who saw it was convinced it was coming from inside the wall. He came out, checked everything, and was super thorough instead of just guessing. Turns out it was actually a leak from the toilet tank that was dripping in a way that made it look like it was coming from the opposite wall. He was super patient with all of our questions and explained the fix. We really appreciated his professionalism and transparency. Having an older home, it can be stressful not knowing what kind of repair you're walking into. I highly recommend him if you want someone trustworthy and knowledgeable who genuinely just wants to help."
