What's this better than the one for 14900 nis? And the 14900 nis you don't have to pay accommodation and shipping they do everything here. What a joke.
Does the 14,900 NIS one have an in-ground installation option? How about בור ע"ג בור? Also, while I realize the steps taken, I'm not sure everyone is OK with making a mikvah out of stainless steel. Again, for a men's mikvah it's much less of an issue, if any, but some people would rather have a mikvah that is kosher for keilim.
