Which electric shower?

Triton T80Z fast fit really easy to install and reliable

 

As above. My experience is that none of them last longer than 5 years on average, so just go for one that has the features you want. Even among the popular models, cost of spares are high relative to the cost of a new unit, so ease of swapping out is high on my list of priority and Tritons EZ fit range win here as they have multiple entry points for water and electricity

 

I fitted a Mira Advance in a flat in 1996. I've fitted 3 replacements, the last in 2023, so they last about 9 years. Really simple to swap in a replacement - just a screwdriver and a spanner.

But maybe Mira are a bit on the expensive side.

 

I personally like the Mira Sport Max 10.8kW Electric Shower, as it has great reviews on Amazon with customers talking about how reliable and easy to install it is. It also comes with an adjustable head and a reassuring 5-year guarantee. I think this would be a great choice for you!
