Excellent replacement

Replaced a cracked seat with this one. The quick-release hinges make cleaning around the bolts so much easier. Highly recommend for anyone needing an upgrade.

Perfect fit for my old toilet

I was worried this wouldn't fit my older model toilet, but the universal design worked perfectly. The thickened material feels very sturdy compared to my previous seat.

Great quality, easy install

Installation took less than 10 minutes. The soft-close feature works smoothly and quietly. Only giving 4 stars because the instructions could be slightly clearer.

Sturdy and comfortable

This seat is much thicker than standard ones. It feels premium and doesn't wiggle at all. Very happy with this purchase for our guest bathroom.

Good value for money

Solid construction and the white color matches our bathroom fixtures well. The lid closes slowly without slamming, which is great for night time use.

After a month of use, it still looks brand new. The thickened design really does make a difference in comfort and durability. Great product from Submarine.
