Is their public showers in Dubai?

Hi every one

I am new to Dubai...knowing little places

I am familiar with Malaysian mosques, which usually include showers, I kinda like to have shower and relaxing after prayer

I have entered now 4 mosques in dubai, and unfortunatly, I didn't find it

is here in Dubai no mosques have a shower? please for the experience here to inform me...as information, I stay near rashidya station, I prefer if mosque very near from metro station

and if there is no shower in mosques, is their any public shower outside mosques in Dubai? I know that some beach do have, but I am not sure which one...and some of them close early

if you know any beach have public shower, and its near the metro station, and close no earlier then 8  or 9 PM, can you please inform me?

Thank you very much..any answer much apreciated
