That is where this Toto kit stood out to me. I made sure it matched my toilet model and seat type before buying, because even a good hardware kit will not help if it does not fit properly.

Check Your Toilet Model
I learned that even when a product is made by Toto, I still need to confirm compatibility with my specific toilet. I recommend checking your toilet’s model number and seat requirements before purchasing. This small step can save a lot of time and prevent the disappointment of ordering the wrong part.
Replacement vs. New Installation
I also considered whether I was replacing old hardware or installing a new seat. If you are replacing worn-out parts, this hardware can be a practical solution to restore stability. If you are starting fresh, I would make sure the seat and hardware are designed to work together for the best fit.
My Final Thoughts
In my opinion, the Toto THU651N Top Mount Seat Hardware for Skirted Toilet is a smart choice if you want a clean, top-access installation for a skirted toilet seat.
