Installing the Wall-Mounted Hand Shower Slider Bar and the Extension Coupler So Nothing Leaks Behind the Tub

Updated September 2026

The Ella hand shower slider bar lets you park the tub's pull-out hand shower on the wall at any height, and it installs with two anchored brackets, a chrome column, a holder, and, most importantly, a coupler and extension line that seal the hand shower's deck receptacle. Skip the coupler and extension, stretch the factory hose to the wall, and water will drip through the deck hole and pool behind the tub. This article covers the slider bar kit and the coupler logic; the hand shower hose, diverter and the full shower column kit are separate articles.

What Is in the Slider Bar Kit

  • 1 chrome-plated slider bar, 24 inches of slide travel (about 27 3/4 inches overall)
  • 1 stainless steel chrome pipe (the column)
  • 1 flexible 60 inch stainless steel hose
  • 1 double-threaded extension pipe (the coupler that plugs the deck receptacle)
  • 2 chrome caps for the brackets
  • 4 wall screws and 4 wall anchors

The supplied anchors and screws are the ones shown in the video. If your wall is tile over a stud wall, drill in the grout line where possible and use fasteners suited to the wall type so the bracket sits flat.

Why the Coupler Matters

On an Ella tub the pull-out hand shower normally lives in a receptacle on the deck, and the hose passes down through that hole. If you lift the hand shower out and hang it on a wall bracket, the hose is pulled up and out of the receptacle, and every drop that runs down the hose finds the open hole and drips behind the tub. The stainless barrel coupler screws onto the end of the factory hose, sits in the receptacle and seals it with its rubber washer; the extension line then runs from the coupler up to the hand shower. The printed instruction sheet is direct about it: do not attach the hand-held shower to the wall unless you have an extension hose with barrel protection. A leak that appears under the tub near the hand shower after a wall relocation is almost always this, and it needs the kit rather than a service call. Other spots to check for a puddle are in water under or behind the tub, and the deck receptacle itself is covered in hand shower leaks at the head or deck.

Watch: Installing the Slider Bar

The video walks through the whole installation. Follow it in this order:

  1. Decide where the column will go and find a perfectly level vertical line. Mark the drill hole for the lower bracket, using the shorter screw.
  2. Drill, insert the anchor and tap it gently until flush. Insert the short screw and tighten the lower bracket to the wall securely, then slide the chrome cover over the bracket.
  3. Set the column into the lower bracket. Before fixing the top, slide the shower head holder onto the column, then place the upper bracket over the column.
  4. Mark the upper drill hole, drill and insert the anchor. The longer upper screw passes through the hole provided in the column and into the anchor; tighten, then slide the chrome cover over the upper bracket.
  5. Remove the hand shower head from its hose and attach the coupler, tightening it securely.
  6. Attach the extension line to the coupler and hand-tighten. Feed the excess line down into the deck receptacle; the coupler creates a waterproof seal at the receptacle and its rubber washer is what makes that seal.
  7. Reattach the shower head to the extension line and place it in the holder. The holder adjusts up and down the column and pivots side to side.

The video also shows what happens when the extension and coupler are left out: the hose is overextended to reach the wall and water runs straight into the deck opening, which it calls a leak hazard.

The Extension Kit on Its Own

This short clip has no written transcript and simply shows the coupler and extension hose being fitted. The printed steps are: unscrew the shower head mixer from the hose, screw the stainless steel barrel onto the end of the hose, screw the extension hose onto the other side of the barrel, place the barrel in the shower base to plug the hole, and screw the shower head mixer onto the far end of the extension hose. The hand shower hose and diverter article covers this kit in more depth.

Slider Bar, Shower Column or Waterfall Faucet?

The slider bar is the simplest way to shower standing or seated with the hand shower you already have, and it can be fitted to an installed tub. The shower column kit adds a 10 inch rain head on a column that connects to the faucet diverter, and because it needs access behind the tub it is best installed before the tub's final placement. The wall-mount waterfall faucet comes with its own 24 inch slider and a wall-fed hand shower, so it never uses the deck receptacle. Wider tubs give more room for a standing shower; see can I shower in a walk-in tub?.

Common Questions

Can the slider bar be added after the tub is installed?
Yes. The slider bar mounts to the finished wall with two anchored brackets and only needs the coupler and extension line at the deck receptacle, so it can be fitted to an existing tub without touching the plumbing behind it. That is the main difference from the shower column kit, which needs access behind the tub. Ask your Ella dealer or the team at (800) 480-6850 about adding one.
Which screw goes where?
The shorter screw holds the lower bracket to the wall and goes in first. The longer screw is for the upper bracket; it passes through the hole provided in the column and into the anchor, which is what locks the column in place. Slide the chrome cover over each bracket once it is tightened.
How high should the bar sit?
Anywhere the hand shower can be reached comfortably from the seat and the hose can still return to the receptacle. Once the column is mounted on a level vertical line, the holder itself adjusts up and down the 24 inches of slide travel and pivots side to side, so the exact bracket height is less critical than a plumb column.
I mounted the hand shower on the wall a year ago and now there is water under the tub.
Install the barrel coupler and extension line from the kit. With the hand shower on the wall, the factory hose has been pulled out of the deck receptacle, and every drop that runs down the hose finds the open hole and drips behind the tub. Once the coupler is seated in the receptacle with its rubber washer and the extension line runs up to the hand shower, the receptacle is sealed and the dripping stops.
Does the waterfall wall faucet need this kit?
No. The wall-mount waterfall faucet comes with its own 24 inch slider and a wall-fed hand shower, so its hose never passes through the deck receptacle. The coupler and extension line are only needed when the tub's deck-mounted pull-out hand shower is relocated to a wall bracket.
Does the kit fit both the 2-piece and 5-piece faucets?
Yes. The coupler threads onto the factory hand shower hose of either set. Because the two sets' hoses differ, tell the team which faucet you have when you request the kit so the right hose and coupler ship together.
Can I use the rain shower column and the hand shower at the same time?
No. The shower column kit's diverter sends water to either the rain head or the hand shower, not both at once, and that is by design. This applies to the column kit rather than the slider bar, which simply parks the hand shower you already have.
What if my wall is tile over studs?
Drill in the grout line where possible and use fasteners suited to the wall type so the bracket sits flat. The anchors and screws supplied with the kit are the ones shown in the video and are intended for solid walls. Once both brackets are secure, the rest of the installation is the same.
