hot & cold running water

[MagpieWench]

Apologies if this has been covered elsewhere, but was making buildings using pathfinder downtime activities and thought...hmmm, bath!

suggestions on making a decanter of endless water do cold and hot water? (ideally with some way to adjust temperature). Was sort of thinking prestidigitation, as that can warm or chill, but it has serious limitations.

Thanks in advance :)

The expensive option always exists: ring gates.

You could create antechambers that fit over the mouth of the decanter that function like Bags of Holding, inside which certain permanencied spells functioned as heating/cooling elements in a massive water heater/cooler. Just fill the antechamber with water and you've basically got a magic water heater.

A continually resetting trap of heat metal in a "spigot" on top of the decanter might work.

these two spells Heat Metal (http://www.d20pfsrd.com/magic/all-spells/h/heat-metal) & Chill Metal (http://www.d20pfsrd.com/magic/all-spells/c/chill-metal) used with a decent plumbing system could basically create hot and cold running water.

Have a decanter continuously fill up a water basin that splits two ways, one towards hot water, one towards cold. At that point just have each faucet/whatnot regulate the amount of hot/cold water they want coming out. Use the magic trap rules to have the spells activate whenever a flap or something is pushed in, IE: whenever one requests water the pressure in that tube would increase, pushing the flap and activating the hot/cold water

A fire? I'm not too familiar with PF, but it should have a way of trapping a small fire elemental or another burning creature.

This is basically what my epic bard did. He used an elevated water tower with any overflow piped to the nearby river, and heat/chill metal on the plumbing system. The decanter could be activated from the castle at anytime to fill the tower. The water was just piped up to it. There was also a permanent custom Purify spell on the tower.

Hot/cold running water.

@ Krobar

You got it. And to your credit, I didn't really think much about adding an overflow pipe (I personally would have just gotten some guy go every morning or hour to check the water levels), but you could potentially use that for non-bath related plumbing.

Having a third pipe go under the building (or throughout it) to constantly clean the... less the desirable waste products... into a separate tank under the building where it's purified (as the water in the initial cistern was) and then seeped into the ground or sent to a nearby river/field could work.

Aaah, Pathfinder. Where the plumbers also happen to be powerful wizards.

Not much else to add, just want to say that Darsson's Fiery Furnace (http://dndtools.eu/spells/shining-south--25/darssons-fiery-furnace--3274/) and Darsson's Chilling Chamber (http://dndtools.eu/spells/shining-south--25/darssons-chilling-chamber--3272/) seem perfect for this, even though Heat/Chill Metal would also do, just because I don't think these two get enough use.

I also vote that you destroy the water instead of purify/filter it, since the Decanter is making it endlessly and you'll have too much on your hands if you keep it. Pipe it into a Bag of Devouring.

What, you expect a mundane to be capable of making something like that that doesn't require a separate water heating area and constant supervision (as it would likely be akin to a giant furnace, burning wood/charcoal to keep the water heated at a good temperature)?

Depending on the building costs you might actually recoup your money relatively fast, when you consider that you don't need to hire the extra hand/s to supervise the heating area or even have to build it (as well as the cost of buying/importing the wood/coal). it's about 3k apiece for each heating/cooling unit.

Note that heating a bath by wood requires a LOT of wood: "And Perlin, in another book (A Forest Journey: Wood and Civilization), said that heating the caldarium of one bath consumed 114 tons of wood per year (http://solarhousehistory.com/blog/2014/1/19/the-roman-baths-and-solar-heating)."

at 2000lbs a ton, that would mean 228000 pounds of firewood used in a year. At pathfinder's 1cp/20 lbs of firewood rate, we're looking at a running cost of:

~114gp/year for the firewood.
three trained hirelings for a year to maintain the heating/area: ~330gp (365x3 silver=~110)

You're saving about 450/year just on heating, plus whatever expenses you would have normally used to build the furnaces and the piping needed to carry the water while it was heating. If you expect the bath house to last 6 years, you've about broken even. Any more then that and you're banking an extra 450gp.

The bath that article is talking about is a large public bath, not your own personal tub or shower. While you were envisioning a bath house, others may have had smaller goals. If all you want is a hot bath, you only need one somewhat-trained servant, a kettle, and a fireplace, and the heat metal trap is a waste of resources.

for anything larger scaled, the heat metal trap is obviously better. You could uplift an entire medieval town with this one trap.

How else-a do dey fitta in ta tubes?
