Will this work with toilets that have a tank?

If your toilet has a tank, you don't need this kit. Standard TUSHY installation connects directly to the toilet's fill valve. This kit is only necessary for tankless, wall-mounted, or flushometer toilets that lack a tank connection.

How far can the sink be from the toilet?

The hose is nine feet long, so the sink's shutoff valve must be within that distance of where the bidet seat mounts. Measure along the path the hose will take, not straight-line distance.

Does this include the bidet seat?

No, this is only the plumbing hardware needed to connect a TUSHY Wave or Oasis bidet seat to a sink's water supply. You'll need to purchase the bidet seat separately.

What if my sink has different sized connections?

This kit is designed for standard 3/8-inch compression connections found in most US and Canadian bathrooms. If your plumbing uses a different size, you'll need an additional adapter from a hardware store.

Flushometer Installation Kit for Wave/Oasis

Most bidet attachments assume you have a toilet tank with a fill valve to tap into. Tankless and flushometer toilets—common in commercial buildings and some modern homes—don't offer that hookup point, which is why standard installation instructions stop short. This kit solves the problem by treating your sink's supply line as the water source instead. The nine-foot hose gives you enough length to route from under the vanity to the toilet without splicing or adding extension couplers, and the brass fittings match the 3/8-inch standard used across North American residential plumbing.

No sizing to guess

Practical upgrade for someone who already owns a TUSHY bidet seat with a tankless toilet.

The details

Tankless toilets, wall-mounted units, and flushometer systems don't have the water reservoir that standard bidet attachments expect. This kit routes the connection to your sink's supply line instead, giving you the nine feet of reach and brass fittings needed to run a clean water line from a nearby fixture.

The polyurethane hose terminates in 3/8-inch brass compression fittings on both ends, sized to match standard North American plumbing. The brass mini adapter splices into your sink's existing connection without replacing the valve or re-plumbing the wall. You'll need access to a sink or other water supply within nine feet, on the same side of the bathroom as your toilet.

Installation follows the same basic steps as a standard bidet hookup, substituting the sink's shutoff valve for the toilet tank connection. The hose is flexible enough to route along baseboards or behind a vanity, and the brass fittings resist corrosion in humid bathroom conditions.

This kit works exclusively with TUSHY's Wave and Oasis bidet seats. It does not include the bidet unit itself, only the plumbing adapters required when your toilet lacks a tank. If you're replacing an existing bidet seat on a flushometer toilet, this is the connector hardware you'll need.
