TOTO BT500B Piedmont Deck Mount Vertical Spray Flushing Rim Bidet

Floor mount with a floor outlet. The Piedmont sets on the finished floor and the waste drops straight down through the slab or subfloor, so it needs a floor rough-in, not a wall carrier. If your rough-in is already stubbed out of the wall for a wall hung bidet, this is not the fixture for that opening.

Five finishes: Cotton White (BT500B#01), Bone (#03), Colonial White (#11), Sedona Beige (#12), and Ebony (#51). Those are TOTO's standard color suffixes, so a Piedmont ordered in #01 matches a TOTO toilet ordered in #01 across the line. Order by the suffix, not by the color name off a screen, if you are matching an existing fixture in a hotel or multi-family unit.

The china arrives with its mounting hardware. Beyond that you are supplying the deck mount bidet faucet set with vertical spray and pop-up, two supply stops and risers for hot and cold, a P-trap for a floor outlet, and a wax or foam seal plus floor bolts if your rough-in calls for them. Confirm the faucet you pick is a bidet faucet with the spray fitting, not a lavatory faucet, since the vertical spray in the bowl is fed from the faucet valve.

If what is coming out is a floor mount, floor outlet bidet drilled for a deck mount faucet, the BT500B is the same configuration and reuses the same style of rough-in. Verify the existing drain location and the faucet hole spacing on your old fixture against the BT500B spec sheet before you demo, because bidet bowls differ in bowl length and hole centers between models and a floor drain is not something you want to move.

Two different products entirely. The Piedmont BT500B is a plumbed china fixture that sits beside the toilet as its own bathroom fixture, with a vertical spray in the bowl and a flushing rim that rinses the basin. It needs its own hot and cold supplies, its own drain in the floor, and floor space. An electronic bidet seat replaces the seat on a toilet you already own and adds no fixture and no drain. If the bathroom is already built and you only want the wash function, the seat route is far less work. If you are building or gutting and the plan calls for a separate bidet fixture, this is that fixture.

Yes, a built-in overflow is part of the china. It carries water off before the basin can fill and spill, which matters because a bidet gets used as a wash basin and gets left running. Pair it with a drain assembly made for an overflow fixture, since a drain without the overflow port will defeat it.

No power at all. The Piedmont is a straight mechanical fixture, no batteries and no receptacle needed, and it does not ship with a battery because there is nothing in it to power. Everything it does comes off the supplies and the faucet valve, so you only need to rough in hot, cold, and the floor drain.

Vitreous china, the same material as a china toilet or lavatory. It is non-porous and cleans with ordinary bathroom chemicals, which is why it is used in hospitality and healthcare. Treat it as china for handling: it chips if you set it down hard or overtighten the floor bolts.

The rim carries water around the top edge of the bowl and rinses the basin down as it fills, instead of dumping water in from a single point. Practically, it keeps the sides of the basin clean between uses, which is the reason spec writers call for a flushing rim bidet in hotel and multi-family baths rather than a plain-bowl model.
