Table showers are common in parts of the US, usually at AMPs (Asian Massage Parlour). It is a separate room with a table and the MA either uses a shower head on a hose, or a pail to get warm water out of a giant bucket. She will soap you up and scrub you nicely, including the good parts. She will then use the pail or shower head to rinse you off. Generally when done you stand up and she rinses you with the shower head to get any soap missed while lying on the table. Some are more sensual than others, I've actually had the MA strip down and do a body slide (and more) in the table shower. I love table showers so much that I have asked for it both before and after the massage and finish. The only place in the area who tried to do this was in Gatineau (old Gatineau) and their table was old and the material cracked so it would "bite" your skin as you moved .... it was a fairly pathetic attempt. I think that was something like 10 years ago, even though I love table showers I did not repeat.
#2 in pulp's list is commonly referred to as a "rain massage". There used to be a place in the west end of Ottawa that did that. No idea if still there. Never tried it as it was reported to be a fairly legit place.
That said, I am heading down to the land of table showers to partake. The places I go have mostly gorgeous Koreans (K girl) who are skilled at table showers, massage and the unmentionable fun that people think does not happen in the US. Happy Canada Day, I will celebrate with a table shower and great massage! :yo:
Unfortunately for the OP I am not aware of any MP in the area offering table showers currently. Hopefully someone will prove me wrong.
