How To Measure Your Elongated Toilet Seat
You’ll need to take accurate measurements to ensure a perfect fit for your elongated toilet seat. Here’s a step-by-step guide to measuring your toilet seat.
- Remove the old toilet seat
The first step in measuring your toilet seat is to remove the old one. Most toilet seats are attached with two bolts that can be easily unscrewed with a wrench.
- Measure the length
Once the old seat is removed, measure the length of the bowl from the center of the bolt holes to the front of the bowl. This measurement will give you the length of your toilet bowl.
- Measure the width
Next, measure the width of the bowl at its widest point. This measurement will give you the width of your toilet bowl.
- Check the shape
Finally, check the shape of your toilet bowl. Elongated toilet bowls are oval, while round toilet bowls are circular. Ensure you have an elongated toilet bowl before purchasing an elongated toilet seat.
How To Choose An Elongated Toilet Seat
When choosing an elongated toilet seat, consider the following factors to ensure the right fit.
- Size
Make sure you measure your toilet bowl accurately and choose a seat that matches the size of your bowl.
- Material
Elongated toilet seats come in various materials, including plastic, wood, and metal. Choose a material that fits your style and budget.
- Shape
Make sure you choose an elongated toilet seat that matches the shape of your toilet bowl. An oval seat won’t fit on a circular bowl, and vice versa.
How Long Is An Elongated Toilet Seat?
The standard length of an elongated toilet seat is around 18 inches. However, some elongated toilet seats can be up to 20 inches in length. Measure your toilet bowl to properly fit your elongated toilet seat.
Can You Put An Elongated Toilet Seat On Any Toilet?
Elongated toilet seats can provide more comfort and room than round ones; they may not fit on every toilet. It’s important to check the shape and size of your toilet bowl before purchasing an elongated toilet seat.
You can use an elongated toilet seat if your toilet bowl is elongated. However, you should use a round toilet seat if your toilet bowl is round.
Remember, different toilet models may have slightly different shapes or dimensions. So, it’s always a good idea to measure your toilet bowl to ensure a proper fit.
Final Words
Most elongated toilet seats have similar dimensions; slight variations can make a big difference when finding the right fit. To ensure a perfect fit, it’s important to measure your toilet bowl accurately and choose a seat that matches the size and shape of your bowl. Find the best-elongated toilet seat for your bathroom and say goodbye to the frustration of ill-fitting toilet seats.
Plumber’s field tip: bring a tape measure to the store — don’t trust the box. I’ve seen ‘elongated’ seats that were 17.5 inches and wouldn’t cover the bowl front. Measure bolt-center to front edge, and check the width. Five minutes with a tape saves a return trip.
