The only hospitals in MD that will allow a VBAC to enter a tub while in labor are Mercy and BWMC, but you have to have a nearly "perfect" combination of low-risk factors, ok it with the Director of Labor & Delivery, and even then they insist that you leave the tub to give birth. Like once you're in the pushing phase it's easy to just stand up and walk to the bed (???). They claim several issues, the main one being what KatyLinda said about constant monitoring (even though both Mercy and BWMC have waterproof telemetry), and the second as it's been explained to me over and over again is that they claim that it's harder to get a VBAC who has ruptured during labor up out of the tub for an emergency c-section.
Basically, the best options for VBAC's in MD are home birth or midwife attended hospital birth, but doing it at home guarantees access to the tub.
