What to know before buying

Listing details to confirm

The listing gives conflicting mounting-spacing ranges: 135-165mm with 150mm recommended, and 135mm-170mm. It also describes a 150 Millimetres mounting-hole diameter, while separately giving the inlet spacing as 150mm. Confirm the required spacing and pipe layout before purchase. The included-components field says “Bath Mixer Tap”, whereas the package list names a thermostatic shower mixer and accessories. The top outlet is G 3/4'' and needs the supplied adapter for G 1/2'' pipework. The listing says hot must connect on the left and cold on the right, and describes different centre-to-top clearances depending on adapter use. Confirm the selected listing contents and installation fit.

Customer feedback highlights perceived good quality, easy installation and satisfactory function, with value for money also noted. These reports may matter to buyers fitting a replacement, but they do not confirm compatibility with a particular pipe layout. The overall rating distribution is mostly five- and four-star, alongside a smaller range of lower ratings, so experiences are not uniformly positive.
