We've been looking for a toilet for a while now - our current one has a leaky cistern, and uses quite a lot of water per flush. It's also 20 years old, and it's huge and ugly.
However, almost all the retailers insist on selling complete bathroom suites - it is generaly more economical to buy a loo, sink and taps (and often a bath too), and then take the bits you don't want to the dump (after all, there is no market in second hand sinks) than it is to get just a toilet on special order. We were looking at toilets that were close to £200, and complete suites for less than that. This is just a crazy situation; it's so wasteful. The sellers try and lure you in with discounts on suites just to make sure consumers waste as many resources as possible.
Luckily, the new B&Q in gillingham now sells 'Toliets to go' for £50. Yup, that's what they call them. It's a complete toilet in a box, with all the cistern fittings etc. And if you just want a cistern float valve or other spares, they'll sell you that too. Amazing - the application of a bit of common sense. Now we've got the almost-as-silly situation where we need to pay a plumber probably double the cost of the loo to install it !
