Why Homeowners Choose Our Shower Plumbing in Ajax

Shower plumbing in Ajax gets sealed behind tile, so it needs to be right before the walls close. Here is what you get when you work with us.

  • Valves Set Before Tile Goes Up

    We set the valve depth, shower head height, and drain location before your tile or wall panels go in, so the trim fits and nothing has to be opened up later.

  • Repair When It Makes Sense

    A dripping or stiff shower often needs a new cartridge, not a new valve. We tell you which one you need and quote it before we start.

  • Red Seal Plumbers, Tested Before We Leave

    Our plumbers are Red Seal licensed and $2M insured. We pressure test new lines and check hot and cold at the head before your shower goes back into use.

Shower Installation and Shower Faucet Replacement Services

We install customer-supplied or store-bought shower valves, trim, and bases. Final price depends on the valve type, wall access, and whether new lines are needed.

New Shower Installation

For a new or relocated shower, we handle:

  • Hot and cold water lines run to the new valve
  • Valve set at the right depth for your tile or wall system
  • Shower head, rain head, or handheld supply placed where you want it
  • Drain connection and venting tied into the existing system
  • Pressure testing before the wall is closed

Shower Valve Replacement

When the valve itself is the problem, we:

  • Confirm whether a cartridge swap will fix it first
  • Replace pressure-balancing or thermostatic valves that protect against scalding
  • Reach the valve from the access side when one exists, to limit tile work
  • Test temperature and flow after the new valve is in

Shower Faucet Replacement

For handles, heads, and trim, we can:

  • Replace a worn shower faucet or handle with matching trim
  • Swap cartridges to stop drips and temperature swings
  • Upgrade to a rain head or add a handheld shower
  • Match new trim to your existing valve brand when possible

Shower Base and Drain Installation

For acrylic and pre-formed shower bases, we:

  • Set the drain where the base needs it, including in basement slabs
  • Install and level the shower base on the drain
  • Connect and test the drain before walls go in

Rain Shower and Thermostatic Systems

For upgraded showers, we install:

  • Thermostatic and multi-port valves with diverters
  • Rain heads, body sprays, and handheld combinations
  • Supply lines sized for the flow your system needs

Shower installation cost in Ajax depends on what is behind the wall. Many standard installs and faucet swaps start at $250. Shower valve replacement and new shower plumbing are quoted after we see the valve type, wall access, and the layout you want.

Common Questions About Shower Installation in Ajax

Many standard shower installs and faucet swaps start at $250. Shower valve replacement, relocated showers, and rain or thermostatic systems are quoted in writing after we see the setup.

It depends on the valve type and how we can reach it. A valve we can reach from an access panel or closet wall costs less than one that needs tile removed. We confirm access and quote before we start.

Often, yes. If there is an access panel or the wall behind the shower is a closet or another room, we can work from that side. When the only way in is through the tile, we explain how much needs to come out before you approve the job.

Common signs are temperature swings, a head that drips after the handle is off, a stiff or loose handle, and weak flow from the shower only. Some of these are fixed with a new cartridge. We check before recommending a full valve replacement.

Usually, yes, as long as the new trim is made for your existing valve. Most brands sell trim kits that fit their own valves. If you want a different brand or style, the valve may need to change too.

Yes. We install acrylic and pre-formed shower bases, connect the drain, and test it, including in basements where the drain is set in the slab.

Yes. We rough in thermostatic and multi-port valves for rain heads, handheld showers, and body sprays, and set them at the right depth for your finished wall.
