Shower & Bathtub Installation in Phoenix, AZ.

What does a shower or bathtub installation involve?

A shower or bathtub installation covers the drain, the valve, the supply lines, and the finished connections. Done correctly, the drain is aligned with the trap so water flows away, the valve is set at the right depth for the wall, and every joint is tested for leaks. Many Phoenix homes are built on concrete slabs, so moving a tub or shower drain may mean cutting into the slab, and that should be planned before work starts. Hard water also leaves scale on showerheads and valves, so we check pressure and flow at the new fixture. Fast Layne Plumbing works around your existing plumbing when we can, to keep cutting to a minimum. We install the valve and drain, pressure test the lines, and confirm the water drains freely before the surround or tile is closed up.

Can you move a shower or tub drain in a slab home?

Often yes, but it takes planning. The drain line may sit under the concrete slab, and moving it can mean trenching. We look at the layout first and explain your options before we start. Larger layout changes are covered under our bathroom remodeling plumbing.

How does hard water affect showers in Phoenix?

Scale clogs showerheads and can make valve cartridges stiff or leaky. A water softener or filtration system reduces buildup on new fixtures.

Are you replacing the toilet at the same time?

It saves time. We can set a new toilet during the same project. See our toilet repair and installation service.

How do we verify the installation?

We pressure test the supply lines, fill the tub or run the shower to check for drips, and watch the drain for slow flow. We test it, rather than assume it works.
