Supporting exposed baseboard pipe over tile (no drilling?)

Remodeling a 100-year-old house and dry-fitting Slant/Fin baseboard. I have a 55" run in a bathroom where half the room has wood base (fin tube + enclosure installed), and the other half is fully tiled.

In the tiled section (tight clearance next to a toilet), I’m planning to run exposed supply/return only—no enclosure. Pipe penetrates the wall at ~9" above tiled finished floor

due to plumbing/electrical conflicts; fin tube elsewhere is at ~3" AFF. Considering offsetting with 45s to hug the corner, or running low and sweeping up (45/90) into the wall.

Suggestions support a ~55" horizontal run of exposed pipe without penetrating tile. Options I’ve considered: standoff/cradle supports, surface-placed raceway/soffit (which is the wood piece in the picture, adhesive-mounted clips, or leave it bare and hung close to the corner/wall.

    Get a "Plastic" slant fin enclosure to hide it.

    I might get a tubing bender from one of your ACR friends that work with line sets for refrigeration and do a custom bend.

    if you want to get really fancy, send the piece out to a shop to have it chrome or brass plated to match the bathroom fixtures.

    Then you just epoxy the split ring hanger flange to the floor. …and Bob's your Uncle!

    After you make that expensive repair and you still have the same problem, What will you check next?

    anything metallic near a toilet can be a corrosion problem

    Slantfin had a painted stainless version for bathroom use

    Pex with composite fittings ?

    it technically only needs support every 10'. you can use plastic anchors in the grout lines of the tile and have it be repairable.

    Should've been addressed before you tiled. Anything you do may be undesirable, and you risk someone stepping on the pipe.
    Any chance you can come out of the wall, go up, and use a flat panel, low profile radiator?
    Or, it looks like it's going to be behind the toilet. I'd drill a hole, and go below the floor, and box it out in the back corner.
    Or get to the pipe on the other side of the tiled wall, re-route.

  • You could also delete the BB and install a towel warmer next to the toilet. Accessories include a toilet paper warmer.
