What it is
Water birth (birth in the tub, versus laboring in water and getting out) has grown in the US as an option in many hospitals and birth centers. Observational studies of screened low-risk populations show comparable neonatal outcomes and less perineal trauma or use of pain medication for the birthing person. ACOG previously discouraged water birth but the 2016 Committee Opinion 594 (reaffirmed 2019) allows immersion during first stage; delivery in water remains debated and depends on setting policy.

Current evidence
ACOG Committee Opinion 594 (2016, reaffirmed 2019) supports first-stage water immersion; RCM/UK NICE guidance and Cochrane 2018 review of water immersion in labor support its safety in low-risk populations.
Where the evidence is clear · where people may choose differently
For most topics, guidelines from ACOG, WHO, and other major bodies broadly agree on the core safety points (when to act in an emergency, informed-consent standards, monitoring baselines). Where reasonable people — and even guidelines — differ tends to be around thresholds (when to start or stop something), preferences (comfort, environment, support), and values (how you weigh small risks against benefits). Use the questions below to explore those pieces with your care team.

- Hydrotherapy — Showers and Tubs in LaborUsing warm water (shower, tub, or peri-bottle) as a non-pharmacologic pain and coping tool during labor.
- Pain Management OptionsAn overview of non-pharmacologic and pharmacologic comfort options.
- Movement & Position in LaborFreedom to move, change positions, and use upright postures during labor.
- Group B Strep (GBS) in PregnancyA common bacteria that lives in the vagina or rectum of about 1 in 4 people; if present at birth it can rarely make a newborn sick, so IV antibiotics in labor are usually offered.
Questions to ask your care team
- ?Does this setting allow water birth or water labor only?
- ?What are the exclusion criteria (GBS, meconium, monitoring needs)?
- ?How is monitoring done in the tub?
- ?What's the plan if we need to get out quickly?
Universal questions (works for any decision)
A short BRAIN-style set you can bring to any conversation about interventions, monitoring, or care decisions.
- ?Why are you recommending this now — is it urgent, routine, or optional?
- ?What happens if we wait an hour (or longer) before deciding?
- ?What signs would tell us this is working — or that we need to change course?
- ?What are the alternatives, including doing nothing?
- ?What would you recommend if this were your family?
- ?What would change your recommendation?
