But the Cherry & Whites were a different side after the break as Jack Spencer, Tom Lushington, and Will Hayward added to Lloyd Evans' first-half score to complete a 34-26 win.
Bath broke the deadlock early on as wing Rees got his hands on the ball and showed great upper-body strength to muscle over - but Rory Jennings' conversion flew wide.
They continued to dominate and a second try followed when prop Guildford collected a neat offload to force his way over, Jennings this time sending his conversion over from the right touchline.
The flowing rugby continued as Bath flew into a commanding lead - this time Herrod-Taylor broke the Gloucester line with ease and sent a pass to Coulsen to dot down, this conversion much simpler for Jennings.
Rees was pushed into touch just shy of a second try and, not to be outdone, Gloucester got themselves on the board soon after.
Fly-half Evans was on hand to finish a flowing move underneath the posts, leaving himself an easy conversion to reduce the gap to 12 points.
Jennings missed an opportunity to extend that lead when he sent a penalty wide but Coulsen soon made amends, grabbing his second try of the half, with Jennings converting for a 26-7 lead at half time.
Gloucester emerged from the break with great intent and Spencer barrelled over the line within the first two minutes, Evans converting despite a troublesome cross-wind.
An excellent last-ditch tackle couldn't prevent Lushington crossing over to close the gap even further, with Evans' conversion bringing them within five points.
And they took the lead for the first time halfway through the second half, full-back Hayward crossing over for Evans to edge the Cherry & Whites ahead.
Evans then added a pair of penalties to take Gloucester more than a converted try clear and that was the way it ended.
