we stayed at graylyns site at martlesham in suffolk in the summer, they have a fab disabled shower/ wet room not the usual small cubicle but a room about 8x8ft, the loo and basin are in there too of course, as i have to assist my daughter, the space made everything so much easier, the showers are coin operated but cost only 20p the site itself is very nice too and onsite wardens were incredibly helpful.
