We are trying to tidy up our wooden house cheaply. The toilet is separate from the bath & shower. When the toilet was installed in the 1950s the building regulation in NZ apparently specified that the outlet pipe had to be in concrete from floor level to ground level, so our sewage outflow is stuck in the middle of a huge concrete pillar right down to ground level underneath the house. The concrete seems to form the base of the (very small) room where the toilet is, although the rest of the house has wooden floors.
Because it is so old the floor and toilet surrounds have a really bad urine smell. We have had a plumber and a bathroom renovator come to look, because we initially thought the toilet must be leaking, but they both said it seems fine and probably the smell has just sunk into the lino and concrete underneath it from 'near misses' on the loo over 40-50 years. We will need to replace the toilet if we can find one that fits (apparently need exactly the same size and orientation because the concrete means that can't be easily changed, although we do have to fix where they recessed the cistern into the wall because apparently it's non-compliant). The bathroom guy suggested jackhammering off the top 5-10cm of concrete and reconcreting it to get rid of the odour from the floor, then laying new vinyl.
This wouldn't fit our limited budget as we'd have to hire someone to do it, so I was wondering, if we can remove the lino is there any type of concrete sealant that a) could be applied to old concrete, b) would block odours and c) wouldn't interefere with the adhesion of new vinyl to the floor?
Also could anyone recommend suppliers from Waikato north for compact floor standing toilets at a reasonable price that we could just get a plumber to install for us?
