Can You Install a Bidet on Any Toilet? Your Complete Installation Guide

Installing a bidet toilet seat is one of the most transformative bathroom upgrades you can make. As bidet popularity continues to grow in the US, many homeowners wonder if their existing toilet is compatible with a bidet attachment. 

The good news is that Coway’s Bidetmegas are designed to work with virtually every major toilet brand and come in two sizes (elongated and round) to ensure a good fit.

 

Universal Compatibility of Coway Bidetmega

Coway Bidetmega bidets (both the 400S and 500S models) are engineered with compatibility in mind. They fit most standard two-piece toilets with either elongated or round bowls. This universal design approach ensures that most homeowners can upgrade their bathroom experience without needing to replace their existing toilet.

 

Four Key Measurements to Ensure a Perfect Fit

Before purchasing your Bidetmega, take these four essential measurements to guarantee compatibility.

 

1. Mounting Hole Distance

The distance between the mounting holes on your toilet should be between 5.23 and 7.9 inches. This standard measurement accommodates the vast majority of residential toilets.

2. Proper Tank Clearance

Your toilet should have between 1.69 and 2.95 inches of clearance between the mounting holes and the toilet tank. This space ensures the bidet can be properly installed without interference from the tank.

3. Bowl Length

This measurement determines whether you need an elongated or round Bidetmega model:

• Elongated toilets: 17.98 to 19.24 inches from mounting holes to the front of the bowl
• Round toilets: 16.59 to 17.85 inches from mounting holes to the front of the bowl

 

4. Power Outlet Proximity

The Bidetmega features a convenient 2-way power cord that extends 47 inches, allowing connection to outlets on either side of your toilet. Unlike typical bidets with restrictive one-way cords, this gives you more flexibility during installation. However, you'll need to ensure you have a grounded outlet within reach of this cord.

 

Toilet Types and Compatibility

Compatible Toilet Types

• Two-piece toilets: These standard toilets with separate tank and bowl components are ideal for Bidetmega installation.
• Most one-piece toilets: Many one-piece designs work well with Bidetmega seats.
• Flat-surface toilets: Your toilet bowl rim should be flat for proper mounting.

 

Potentially Incompatible Toilet Types

• French curve toilets: These have a non-standard curved design that may not accommodate the bidet attachment.
• Wall-mounted toilets: Some wall-mounted models may require special adapters (check manufacturer specifications).
• Toilets with integrated bidets: These already have built-in bidet functionality.
• Non-standard designs: Unusual shapes or custom toilets may not fit standard measurements.

 

Easy Installation Process

One of the best features of the Coway Bidetmega is its user-friendly installation process. Most users can complete the installation in under an hour with just basic tools.

 

 

1. Turn off the water supply to your toilet
2. Remove your existing toilet seat by unscrewing the mounting bolts
3. Attach the mounting bracket included with your Bidetmega
4. Connect the T-valve to your toilet's water supply
5. Mount the Bidetmega onto the bracket
6. Connect the water supply hose from the T-valve to the bidet
7. Plug in the power cord to a nearby outlet
8. Turn the water back on and test all functions

The Bidetmega comes with detailed instructions and all necessary hardware for installation. No special plumbing skills or professional assistance is typically required, though professional installation is available if preferred.
