If your toilet pan is still okay, just replacing the faulty cistern can be a cost effective solution.

Minimal disturbance to wall finishes in bathroom/toilet.

Tip! Use a wider cistern to cover unpainted wall behind existing cistern.

The cisterns come with new seats and fittings.

Another idea to spruce up a tired bathroom on a budget.

The porcelain cisterns come in a rounded or square edge finish. The plastic come in rounded finishes.
