Luckily there is no fixed bottom, just a based which it sits on. However, tipping it on its side is an issue as it is quite an old, round spa with a fairly weak facade (see picture). It was a real effort to get it out of the seller’s garden and into ours! The only time I want the thing moved again is when it has given up the ghost and it is going to the tip to be replaced by a shiny new one!
Bush fix sounds great, full repair by a tech sounds horrible, whichever currency we’re talking. Ultimately, it is a 15 year old (albeit in very good condition for age) hot tub so we need to be careful how much we spend on repairs. May have to try the bodge fix first of all!
