Rubber Toilet Seat Well Nut Fittings – Top Fix Expansion Plugs for Roca

These are not made by Roca, but they have been found on a number of Roca toilet seats

• Allows you to repair or renew a toilet seat for a back to wall pan, without having to remove the pan from the existing plumbing system. Eliminating the need for a plumber!
• Not only for back to wall pan but pans with fixings that are hard to get to or hard to see. Hence the name Blind Fixings.
• Instead of buying a top fix toilet seat, which can be costly simply purchase a cheaper one and use these fixings instead of the ones that come supplied with the seat. Saving you money.
• Simply push the rubber Gromit through the hole in your pan. Place the seat on top and use the bolt supplied with our kit instead of your normal fixings.
• As you tighten the bolt up, the brass inserts at the bottom rises expanding the rubber ball creating a tight fitting. Therefore, eliminating the need to tighten any bolts underneath. (Top Fix)

Please check before buying that these are compatible with your new or existing toilet seat. There should be one bolt for the fixing straight through the pan. You may need to use part of your existing fixings with this new kit.

Details

These Rubber Well Nut Fittings provide a professional-grade, high-grip solution for mounting toilet seat hinges to blind-hole pans. Specifically, the heavy-duty rubber sleeves are designed to expand and “lock” into the porcelain as the bolt is tightened. While these are a high-quality alternative part, they are widely recognized to fit popular branded suites, including Roca. Furthermore, the rubber material provides a natural cushion that prevents the hinge from shifting. Consequently, they represent a durable, non-slip upgrade for modern back-to-wall toilets.

Fixing a sliding toilet seat on a branded pan often reveals a frustrating search for specialized parts. Specifically, many generic plastic fixings fail to grip the smooth interior of a Roca or similar high-end ceramic hole, leading to a seat that wobbles within days. This constant movement is not just annoying; it puts unnecessary stress on the hinges, eventually causing them to snap. Moreover, genuine branded replacement kits can be expensive and hard to find. However, these Rubber Well Nut Style Fittings eliminate this struggle entirely. Because the rubber sleeve compresses and “bites” into the ceramic, it creates a much stronger friction-lock than plastic. Therefore, you restore the original stability of your premium toilet seat for a fraction of the cost.
