Question: Are the bolts that are used to fasten the toilet plastic or stainless steel?
Document: I don't know what is up with the low-flow flush toilets, but it seems like they are the reason for urine splash-back onto toilet seats. (I have never had this dilemma in an older house.) I was going crazy, wiping down the toilet seat often - and always when I used it. Regular toilet seats develop stains after awhile, and that is such a turn-off. I like a clean bathroom, and I felt like I was losing a battle.
Excellent quality and beautiful craftsmanship. My original was plastic and recently highly modified by my puppy. She has not been interested in this one, yet. Installed easily and is solid and stable.
High quality, comfortable seat and hinges don't flex like seats having plastic seats and hinges. Worth the extra cost, plus with the open front there's more room for your thingy. Women buyers take note, this makes a positive difference for males.
I just got a new toilet and the seat provided was flimsy and small size. The new one works very well!
They should outlaw the old style toilets. This open front toilet is perfect if there is a man in the house. No more scolding from the wife for urine splatter on the seat. My &#34;boy&#34; also has room in the front and doesn't touch the seat like it did with the old toilet seat. It cleans easily and does not stain. The finish is exceptional. The hinges are chrome and heavy duty.
What can I say!! It's a toilet seat... however, because my spouse likes the elongated open front, this toilet seat is a good one. It is nicely made; good materials; good price AND it came with a lid. Don't laugh... go to your neighborhood hardware and see how many of these types don't come with the lid. I would recommend this Kohler toilet seat.
The open front is convenient for the males in my family, and I am very pleased with my purchase. The hardware is metal, easy to install. It has been easy to keep hygienically clean. It serves my purpose.
Easy install, great looking and is exactly what I needed....  Seat is a little thinner than I expected, compared to my older standard (non open front) seat, but very sturdy.
Answer: no
