It was a dream start for the Baggies as Torbjorn Heggem nodded home his first goal for West Brom via an Alex Mowatt corner.
The Hawthorns was electric after the Albion took the lead, however, a lack of concentration saw the visitors score twice in two minutes, taking the lead and stunning the home crowd.
West Brom started the second half on the front foot as they searched for an equaliser which eventually came in the 62nd minute.
Tom Fellows' deflected shot looped over the Blades goalkeeper and sent the Hawthorns into bedlam.
It is another point on the board for Carlos Corberan's West Brom, who move to within two points off the play-off places.
Player ratings
Alex Palmer - 6
A stunning second-half save kept the Baggies in the fixture but Albion's number one arguably could have done better to prevent the two goals.
Kyle Bartley - 7
The team captain started the game strong as he commanded the backline limiting Sheffield United's offensive approach and high press.
Bartley has done well to fit back into the starting 11 after a period of time away due to injury.
Torbjorn Heggem - 8
Heggem opened his West Brom wich Albion account as he powered home a header in the first half to give the Baggies the lead.
A miscued pass by the Norwegian did end up giving Sheffield United their second goal of the afternoon but he made up for his mistake by nullifying the Blades’ attacking threat in the second half.
Callum Styles - 7
It was a strong performance from the Hungarian once again, who was very good in starting the attack down the left-hand-side.
His final pass could be improved but for the most part he has been playing well in recent weeks and that continued.
Darnell Furlong - 7
Albion's full-back was excellent throughout the course of yesterday's game and kept the same top-form he has had all season. The Englishman was excellent going forward with multiple great threaded passes to winger Tom Fellows.
Jayson Molumby - 6
The Irish midfielder played well and exemplified his high work rate and stamina as well as putting in some great challenges throughout the game.
However, his anger seems to get the better of him at times as yesterday's opponents seemed to rile him up, putting him at risk of talking his way into the referee's book. Luckily for Molumby, this wasn't the case during the clash with the Blades.
Alex Mowatt - 8
Mowatt delivered a brilliant cross into the box from a corner, gifting teammate Heggem with his first West Brom goal.
Alex Mowatt has been an integral part of Corberan's midfield and squad this campaign. The Englishman picked up his first assist of the season and looks to be in an incredible form.
Tom Fellows - 8
Fellows found himself constantly beating his opposition and helped win the corner for Albion's first goal.
The winger's second-half strike deflected off of a Sheffield United defender and looped over goalkeeper Michael Cooper giving West Brom the equaliser they had been hunting for.
Mikey Johnston - 7
The winger completed the most dribbles (4) in yesterday's game.
Johnston played very well and helped create West Brom's second goal after picking the ball up in his own half, dribbling and keeping the ball to allow Josh Maja and Tom Fellows to burst into the opposition's half.
Karlan Grant - 9
Arguably, Grant has been Corberan's best player this season and we saw why yesterday. He has been a completely different player this season, his work-rate has been second to none.
The winger was making runs in behind Sheffield United's defence as well as tracking back to relieve pressure off of his defence. Grant played extremely well and has continued to keep his red-hot form.
Josh Maja - 8
The Nigerian striker drops deeper to create chances for the midfield to play the ball into feet for Maja to turn and offload to another teammate. We saw a prime example in this yesterday as he did this to claim an assist for Tom Fellows' equaliser.
