ProfessionalBidet Attachment Installation

Bidet attachments are one of the easiest bathroom upgrades to live with once they're in — and one of the easiest to install incorrectly. We handle the shut-off, T-valve connection, and seat swap so everything fits snug, doesn't drip, and is ready to use the same day.

How it works

1

Shut off and prep

We close the toilet's supply valve, flush to empty the tank, and disconnect the existing supply line to make room for the T-valve.

2

Install the T-valve and unit

We attach the T-valve, reconnect the supply line to both the tank and the bidet, then mount the bidet attachment or seat to the bowl.

3

Test and adjust

We open the supply valve, check every connection for drips, and test the bidet's spray to confirm pressure and positioning feel right.

We can help

Problems we fix

  • T-valve that leaks at one or both connections because threads weren't sealed
  • Bidet seat that doesn't fit the toilet bowl shape (round vs. elongated)
  • Supply line kinking after reinstallation, reducing pressure
  • Attachment that shifts because mounting brackets weren't tightened properly

Good to know

Bidet Attachment Installation — FAQ

Will a bidet attachment work on any toilet?

Most non-electric attachments fit standard two-piece and one-piece toilets with a shut-off valve nearby. Electric bidet seats need a grounded outlet within reach — we check this before starting.

Do I need to buy the bidet before you arrive?

Yes — there are many models at different price points, and the best choice depends on your toilet shape and budget. Purchase yours and we'll install it correctly.

Is the installation messy?

Not at all. We work entirely under the tank and at the supply line — no cutting into walls or floors. The toilet stays functional the whole time.
