I've got three Albion baths. None of them are tubbys though.
They're OK. I would have gone for cast iron bath co but given one had to go to the 2fkoor of the house and two on the first floor and they would need to go vertical to turn on stairs, I didn't want one of plumbers squashed under one.
Albion are sold as a solid but lightweight alternative to cast iron.
They look exactly like the cast iron baths. But so much easier to handle.
However the insides are very shiny and look like plastic (not really great when you've spent £8k on three bath tubs).
And they don't sound particularly solid either when knocked so their own "passes the knock test", isn't really entirely correct.
Very very over priced imo. But they really are far far nicer than acrylic.
I'd say they're easier to clean than cast iron as cast iron baths don't like most cleaning fluids or bleach (ruins the enamel).
And the fact you can install them without worrying about getting them carried into the bathroom or injuring someone in the process.
Our last house I didn't go for Albion but a cast iron bateau. Beautiful but the poor plumbers plus 6 of his friends almost killed themselves getting it up the stairs and the stair case needed a repair afterwards.
So beautiful, better than acrylic and easy to maintain. However they don't quite match up to a cast iron bath in terms of looks.
Btw this is being hyper critical. I suppose I think they are over priced. If they (not that it would happen), were approx 15% to 20% less then it wouldn't be such a wrench. And I would be much more glowing in my feedback.
If you live in a flat they are a fab option and will look great.
