Las Vegas Commercial Plumbing Contractors
Restrooms, break rooms, kitchens, and medical plumbing for Las Vegas build-outs.
Plumbing is one of the harder trades to change in an existing building, because drains run under the slab and water lines run through walls and ceilings shared with other tenants. Getting the plumbing plan right early keeps a Las Vegas build-out on schedule and on budget.
Our network’s licensed plumbing contractors handle restrooms, break rooms, restaurant kitchens, salons, and medical and dental suites across the valley.
Restrooms and Accessibility
Most tenant improvements add or update restrooms. Typical work includes:
- Fixture counts based on occupancy
- Accessible restroom layouts and clearances
- New water closets, lavatories, and urinals
- Grab bars, accessible faucets, and mirrors
- Floor drains and waterproofing where needed
Accessibility items are checked closely during plan review and final inspection.
Under-Slab Work
New plumbing locations often mean cutting the slab:
- Slab scanning before cutting to find tendons and conduit
- Trenching for new waste and vent lines
- Tie-ins to existing mains
- Backfill and slab patching
- Coordination with flooring so patches stay flat
Many buildings in the valley use post-tensioned slabs, so scanning before any cut is essential.
Restaurant and Food Service Plumbing
Food service tenants carry the heaviest plumbing scopes:
- Grease interceptors sized for the kitchen
- Floor sinks and indirect waste connections
- Three-compartment and hand sinks
- Gas piping for cooking equipment
- Coordination with Southern Nevada Health District requirements
Grease interceptor size and location affect the whole kitchen design, so they are decided early.
Hard Water and Water Heating
Las Vegas water is very hard, which affects equipment life:
- Water heaters sized for the actual demand
- Water treatment or softening where it makes sense
- Mixing valves for safe hot water temperatures
- Scale-resistant fixture choices
- Access for maintenance and flushing
Planning for hard water up front extends the life of heaters, fixtures, and equipment.
Medical, Dental, and Specialty Plumbing
Some uses need more than restrooms and sinks:
- Plumbing at exam and treatment rooms
- Dental vacuum and air line coordination
- Salon shampoo bowls and hair traps
- Lab sinks and specialty drainage
- Eyewash stations where required
Specialty plumbing is coordinated with the equipment supplier before rough-in.
Backflow, Testing, and Closeout
Before the space opens, plumbing systems are checked:
- Backflow prevention devices installed and tested
- Pressure tests on new piping
- Rough and final inspections
- Fixture operation and hot water checks
- As-built locations of new lines
A documented, tested system protects both the tenant and the building.
Frequently Asked Questions
Do I need a grease interceptor?
Most restaurants and many food service tenants do. The size and type depend on the menu, fixtures, and local requirements, and it is one of the first items to settle in a kitchen design.
Why do plumbing changes cost more in existing buildings?
Drain lines run under the slab, so new plumbing locations usually mean scanning, saw cutting, trenching, and patching. Placing restrooms and sinks near existing lines keeps costs down.
How does hard water affect my equipment?
Las Vegas water carries a lot of minerals, which builds scale in water heaters and fixtures. Water treatment and regular maintenance help equipment last longer.
