Costs may vary depending on the product grade, drainage method, installation conditions, and whether interior work is required.

* In the case of apartments, construction details and delivery methods may be specified by management regulations.
* The warranty for construction varies depending on the content and location of the work.
If you send us photos of the construction area, floor plans, approximate dimensions of the toilet room, drainage positions, etc., we may be able to provide a rough estimate.

Toilet Replacement Construction Achievements
Due to dirt and deterioration from long-term use, we carried out a toilet replacement project.
We conducted replacement work due to water leaks from the deterioration of the water supply connection and issues with the warm water washing toilet seat. Along with the toilet replacement, we also replaced the wallpaper and flooring.
When to Replace a Toilet
The timing for replacing a toilet depends on usage and maintenance conditions, but a general guideline is around 10 to 20 years.
The toilet bowl itself can last a long time, but components inside the tank, water supply pipes, shut-off valves, and warm water washing toilet seats may deteriorate faster than the toilet bowl.
If you notice any of the following symptoms, please consider repair or replacement.
- Water is leaking from the toilet
- The toilet water won’t stop
- The warm water washing toilet seat is not functioning
- Poor flushing or frequent clogs
- Strange noises or odors are present
- There are cracks or damage to the toilet bowl
If the number of years since installation or replacement is short, or if issues arise despite infrequent use, you may be eligible for manufacturer warranties or construction company guarantees. Before requesting paid repairs or replacements, we recommend checking your warranty or construction contract and consulting with the installation company or manufacturer.
Leaving water leaks unattended can lead to corrosion of flooring materials and substructures, as well as leaks to the lower floors. If you notice any abnormalities, please consider inspection or replacement as soon as possible.

What is a Toilet?
A toilet is a residential fixture composed of a bowl, tank, seat, water supply pipe, and drainage pipe. Common types of toilets include those that combine a bowl, tank, and seat, integrated bowl and seat types, and tankless types without a tank.
Recent toilets often come equipped with features that prioritize cleanliness and ease of use, such as the following.
- Water-saving features that help reduce water bills
- Automatic cleaning that flushes after use
- Automatic opening and closing of the lid
- Deodorizing function that minimizes odors
- Warm water washing toilet seat and heated toilet seat
- Stain-resistant coating that makes it hard for dirt to stick
Points to Note for Toilet Replacement Work
Toilets can have “floor drainage” that drains to the floor or “wall drainage” that drains to the wall. For floor drainage, check the “drainage center” from the wall to the center of the drainage pipe, and for wall drainage, check the height from the floor. Products that do not match cannot be installed as is.
Check not only the width but also the height, depth, and space in front of the toilet. A warm water washing toilet seat requires a grounded outlet, and some tankless models may not be installable depending on the water pressure.
If the new toilet is smaller, dirt, discoloration, and screw holes that were previously hidden may become visible. If you are replacing the interior, doing the work with the toilet removed will allow for a clean finish under and behind the toilet.
It is recommended to replace the interior at the same time as the toilet replacement
If you carry out interior work after replacing the toilet, there may be additional costs for removing and reinstalling the new toilet. If you are concerned about the deterioration of wallpaper or cushion flooring, replacing them simultaneously can keep construction costs down while making the entire toilet space look clean.
Moving or adding installation locations, in the case of apartments
If you are moving the toilet’s position or adding a new one, it will be necessary to install or relocate the water supply pipe, drainage pipe, outlet, and ventilation equipment. In apartments, construction details may be specified by management regulations, so it is also necessary to check with the management company or management association in advance.

We will check the drainage center, space, and outlet during the on-site survey
Toilet Replacement Work Procedure
Before construction, signs of aging such as dirt, deterioration of internal tank parts, and issues with the warm water washing toilet seat can be observed.
Since there may be water remaining in the toilet bowl, we carefully remove it to avoid making a mess. After removal, we clean the floor of any dirt and old fixing materials to prepare for the installation of the new toilet.
After removing the existing toilet, we check the condition of the drainage pipe, water supply pipe, and stop valve. If there is any deterioration or damage to the parts, we replace them with new ones. If the drainage position of the new toilet differs from the existing one, we use a drainage adjuster for renovations to make the necessary adjustments.
If there is any corrosion or damage to the floor, we will repair the floor before installing the toilet.
We align the new toilet with the installation position and securely connect it to the drainage socket. We check that the toilet is not misaligned or tilted and fix it to the floor using dedicated fixing brackets and screws. Careful installation is necessary, as gaps or misalignments in the drainage connection can lead to leaks or unpleasant odors.
For combination types, attach the tank to the toilet and connect the water supply pipe. Then, connect the warm water washing toilet seat, water supply hose, power source, and ground wire, and if there is a wall-mounted remote control, confirm and install it in a convenient position.
For tankless or integrated toilets, connect the main unit, water supply section, power source, etc., according to the product installation manual.
Open the stop valve to allow water flow and check for leaks from the water supply pipe, stop valve, tank, toilet, and drainage connection points. Also, confirm that the warm water washing toilet seat operates without issues, then clean up to complete the job.
