I'm flying into LHR from CPT but on Y Fare, I have *G and PP but can't see any options for getting a shower on arrival which would be great because I'm headed into a full day.

Covid killed the plaza arrival lounges and the other arrivals lounges seem to be business only.

Any suggestions? Anyone know of a good shower in LHR arrivals or a nearby hotel (Day rate room seems a bit excessive tbh).
