How to Install a Floor-Mounted Bidet: A Step-by-Step DIY Guide 2026

Installing a floor-mounted bidet is a practical home improvement project that adds both comfort and value to your bathroom. Whether you're upgrading an existing space or finishing a new one, this guide walks you through every step—from gathering tools to securing the fixture. For all your home improvement needs, we've got you covered with quality supplies.

What You Need for Bidet Installation

Before you start, gather these essential items. You can find many of them in our home improvement collection:

• Floor-standing bidet
• Check valves (for hot and cold water)
• Flexible hoses, conical joints with gaskets, drain fittings
• Single-lever faucet, pop-up drain assembly with mechanism
• Wall plugs with blind nuts
• Thread seal tape
• Pliers, fork wrenches

How a Bidet Is Constructed

A bidet can be wall-hung or floor-mounted. This guide focuses on the latter. Before final fixing, you must install the drain assembly and complete faucet. The drain usually comes with a pre-oriented gasket for connection. Faucets—whether single-lever or with a central mixer—are installed the same way: insert from above through the hole in the ceramic, placing two rubber gaskets—one above (between faucet and ceramic) and one below (between ceramic and tightening nut).

Before positioning the bidet, also mount the first part of the trap (usually two pieces). Finally, secure the bidet to the floor using appropriate plugs, finishing the joint line with the tiling using a multi-purpose sealant.

Step-by-Step Installation

Mounting the Check Valves

The bidet requires three connections: hot and cold water supply and drain. Screw the check valves onto the hot and cold water supply pipes on the wall. For reliable plumbing parts, browse our home improvement supplies.

Drilling the Floor

Place the bidet in position and mark the floor through the fixture's holes. Drill the floor to insert plugs that will lock the bidet in place. A sturdy shed or greenhouse might not be needed here, but for outdoor projects, check our garden supplies.

Fixing the Faucet and Drain

On the bidet, install both the drain and the single-lever faucet with its hoses, as well as the pop-up mechanism. Shape the faucet hoses to avoid kinks.

Fixing the Conical Joint

At the outlet of the wall-mounted valves, screw the nut that accompanies the flexible hose, or the conical joint of the chrome-plated copper pipe coming from the single-lever faucet.

Securing to the Floor

After inserting plugs into the floor holes and fitting the curved part of the trap, secure the bidet. For a complete bathroom refresh, consider our bathroom vanities and mirrors.

Finishing Touches

Apply thread seal tape to all threaded connections to prevent leaks. Use a sealant along the base where the bidet meets the floor for a clean, waterproof finish. To complement your new bidet, explore our lighting and wall decor collections.
