Handle9:timmmay: Why didn't you like the shower dome?
In IMO they are incredibly ugly. If you've spent serious money to install an attractive bathroom with a tiled shower with frameless glass there's no way I'd be putting a big lump of plastic on top of it.
To each his own. I've used them for a number of years, even making one for a rental flat once. The effect was almost instant in reducing moisture in the house (in Auckland) which made the heating more effective, and less costly. Sure the glass sides of the cubicle 'steam-up', but the mositure on them is no different from that on a hard (non see thru) wall or shower curtain.
Current place I'm in has shower domes and general extractor fans in the bathrooms. 10 year old house, single glazing, bathroom windows never/rarely opened, no mould or moisture issues.
