How much would you expect to pay for 4 bubble top with underside drainage rubber mats, the thick black heavy ones, apparantly they will a 12x12 stable with a gap at the front left. Very good condition.
Are they new or S/H? New, I'd say £45-£50 per mat. S/H maybe £30 per mat. Really wouldn't know S/H. I'm talking about the decent ones with what looks like 2p pieces on the bottom for good drainage. they weight about 7-8stone a mat!
Word of warning... Mats are usually 6ft x 4ft, therefore you'd need 6 to fit a 12x12 stable.... I'd check the sizing. I would strongly recomend you don't fit them with any gaps. Otherwise you will be cleaning under there all the time cuase it will smell so bad! And you really don't want to be doing that with the heavy ones, they need to be fitted as tight as possible.
