We are about to rent a house which has two bathrooms that only have showers, not tubs. The shower area is "tub sized", but no tub. We have a toddler who loves his baths, are are trying to come up with a solution. The baby tubs are all way too small for him, and the adult sized inflatable tubs we've seen (that are used for people who are disabled to bathe them on their bed) are too large for the bathroom. Any ideas? It cannot be anything permenant as we are only renting short term.
