If you are going to develop b/w film negatives, then absolute temperature control is not needed. B/W film can be developed just fine over a range of temperatures, you just adjust the time in the developer to match the temperature of the developer. The worst case would be if your room is quite warm, and you would need to chill your developer first. (Put in fridge). Once the film is fixed in a hardening fix, such as Kodak Rapid Fix & Hardener, then you can even wash the film over an even greater temperature range safely.
Even modern E-6 color slides can be successfully developed at home, as well as C-41, and several manufacturers market developing kits specifically for the amateur who would need small quantities and less precise temperature control.
Basically, the standard E-6 and C-41 (transparency and color neg chemistrys), require a developer temperature of 100f, which is relatively easy to maintain, by putting your bottles of chemicals into a deep tray (such as a dishwashing tray), in a sink with the faucet running continuously keeping the tray full of tempered water, allowing the tray to constantly overflow into the surrounding sink or bath-tub.
In my opinion, color film developed with "FRESH" chemistry is better than having the same film developed at mini-labs with their machines and "replenished" chemistry, which often does not get replenished correctly.
The best results from your film will be achieved when you learn to develop the film yourself, rather than rely on mini-labs, as (even with color) you can tailor your developing to fit your style.
Now, with the advent of extremely high quality scanners at reasonable prices, the the whole process of developing and printing at home can be quite a fun task, and not take up nearly as much room as it did when the only way to get prints was to make wet prints with an enlarger.
