I'm thinking of doing the same to house a downstairs toilet/walk-in
shower. What sort of size and budget do you have in mind.

The merits or demerits of having thermal mass (blockwork) inside the
insulation have been well discussed before. Essentially it slows the
warm up time and it slows the cool down time and may make a house a bit
cooler in summer.

It's ideal for rooms in constant use as it helps keep the temperature
even. Its bad for an occasional room that you want to warm up quickly.
